Crash Course: APIs w/ Facebook & Twilio

1. What Are APIs [8:12]: - Hey, - Chris here. - Welcome the crash course AP Eyes and interactive data. - So I'm really happy to be teaching this course. - I've been teaching it for about a year now as part of my programming for non programmers - workshop. - And, - um, - it's it's been going really well, - like, - because I know how hard a B I's can be if you're not a programmer and even some beginner - developers or even some higher level developers. - Um, - how does trouble with understanding AP eyes? - It could be a bit complex. - And so what I want to do here in this class is understand what are AP eyes right? - How can we use them in our project and to just, - conceptually understand you know how to get started? - What is the best practices? - And to that end, - we'll be looking at a lot of examples a lot of real life examples, - but we'll also be looking at code. - And so, - even if you're not a developer, - I think the best way to understand this stuff is just to get in and actually see it. - Um, - I mean, - slide slide presentations and books they helped will give us some theory, - the supporters, - but we actually want to apply and do something with it. - So we'll be doing a little bit of both, - um throughout and just, - you know, - let's get started. - What are AP? - Eyes. - Okay, - so maybe you've heard someone say Yelp has an A p I we can use or The New York Times is an - A p I we can use. - What does it mean when there's an AP I? - Well, - really All this person means is that there's some data out there, - right? - You can imagine Yelp has some data that they want to get to us. - So yelp, - if you ever been there, - has a lot of data about restaurants, - you know all over the city all over the world and reviews that their customers come and - give reviews for different things. - Different comments. - Wouldn't it be awesome if we could get some of that data? - Right? - Maybe I'm making a project, - and I want to include, - you know, - reviews of the city. - I have maybe, - ah, - real estate app. - And I want to show people. - Yeah, - you know, - there's also really awesome restaurants on this street, - right? - Or there's really good bars in the street. - You know, - I could find that data. - Where would I get that from? - I don't want to. - Like, - added in myself, - right. - We take a lot of time to make my own database on my own data collection. - I don't go around the city and, - like, - write those all down or Google map it for a day. - But Yelp has that, - and they've organized it for you. - And so we could take that data and we could bring that into our project. - That's the power of AP eyes being able to access the data that Yelp has right being Evel - access to data that Google as that Facebook has about our friends, - right? - Twitter, - tweets, - different stuff. - We can use all of that data in our own projects, - and that's exactly what people are doing. - So with Yelp, - for example, - you can see here the scenario I just described. - I can see that there's court bars and restaurants in the area, - right? - And they have some like four stars. - Things are cool. - I could look more and then go. - Yeah, - you know, - maybe I want to buy a house around here, - right? - Truly, - I didn't need to go and find out this stuff themselves. - They just queried the yelp ap I grubhub will show you. - Hey, - if you wanna take take out right, - we'll tell you. - You know, - these are the reviews that people are giving it on Yelp. - Their business is just about helping you get, - you know, - take out from restaurants making easy online or from your iPhone. - But they don't want to worry about reviews, - so they just take that data from Yelp. - An FBI is like a bank vault, - and it's true, - Um, - when you go to the bank to get money, - right, - this is what we're gonna call the human AP I experience. - Right? - This is something you do, - You go to the bank, - you get out money. - Well, - how do you do it? - Let's look at this example. - I think this will help us understand. - Ah, - human ap, - I so that we can understand what are really a p. - I is. - And so when you go to the bank, - you walk into Bank of America, - you enter the vault, - you take $20 then you go out and you know you go to the restaurant. - You spend that money that's like a normal day, - right? - Totally not correct. - Now we don't do that. - What do we do when we go to the bank? - We don't go into the vault And why? - Well, - obviously, - it's There's other people's money in there, - and then yours, - right? - Then the bank doesn't want you to possibly steal that or to take too much, - right? - They need to monitor that. - And so how do we get our money out of the bank? - What? - We use an interface in this interface, - right? - The A T M. - And now what do we do with the mall? - I take out my card and I put in my pin number, - and then it knows its crest. - It's like a It's Chris. - And then it just allows me to take the money I have access to. - And even in these denominations, - right, - I can only kind of take out, - like, - 20 or 40 maybe somewhere up to 400 for a day, - right? - If you've ever had kill large sum of money out, - you know you have to do different days, - day by day. - Yeah, - and so they they basically limit you on how much you could do and on who it is, - Right? - This is important in this scenario of this human, - A p I. - The person making the programming here are the completing. - The task is you. - You're coming to the bank pressing the buttons. - It's going to the vault, - right? - The month metaphorical vault here, - and it comes back and you get your $20 bill. - This is a pretty common experience. - Now, - let's look at this as if it were data, - right? - And what was in the database was data we wanted access to. - This is exactly how on a P I works. - So here we want to get out. - Data. - Let's say that I want to get my most recent tweets. - So what do we dio? - Well, - every a p. - I is gonna have an interface right the way that we can get to that data they're all gonna - have, - For example, - a developer site, - right? - A developer site is gonna have a way that we can find out. - How do we get that data from the database? - And so we'll go here, - for example, - to the Twitter's developer site. - Right, - Steph, - not twitter dot com and we'll find out how to get access to our data and what we right here - is some code to complete the program, - right. - So we're basically writing code on our behalf to say, - Hey, - this code is gonna go to Twitter and it's gonna come back with a tweet, - or it's gonna come back with some D m's right or some data. - Maybe all my tweets are gonna come back. - Whatever it is, - we write that in the code, - and that's the task. - Were writing. - And this is how a common AP I call is made a p I. - What does it stand for? - I'm not usually the type of person that teaches and explains what all of these letters mean - . - Html XML. - It's usually not that important, - but with a P I I'd like to explain because I think the letter I an a p I is important to - understand this interface right application programming interface, - and you can see it already. - We've talked about the interfaces that we use to interact with our data. - Really, - any project you make any Web project. - It's all about the data, - right? - It's a lot of the data that we want to get, - whether it's users, - whether it's a transaction and then we see it through different interfaces. - A website iPhone, - for example. - Let's check Twitter on her iPhone, - right? - And we see this display here. - Let's check Twitter on tweet deck. - Let's check Twitter on Twitter, - right? - There's lots of different places that you can interface with Twitter. - What do I mean? - Well, - all we're talking about is some data, - and the data base here is common, - right? - It's going to stay the same for all of these. - So it doesn't matter where you check Twitter where you update it. - All you're really doing is finding a way to interface with the data in the database. - And so we need to understand a little bit more about databases and how they work and then - come back to understanding how interfaces work with the data. - But that's the flow that we're looking at here with. - AP eyes interfacing with data 2. Databases Part 1 [14:16]: - Okay, - So let's understand a few fundamental things about databases, - and this will set the foundation for when we move forward and talking with AP eyes. - This will give us a sense of some of the vocabulary and concepts that are underlying really - any website or Web service. - So databases. - Well, - let's take an example of the difference between front end back end and how databases - interplay with website. - Here we have Zappos, - and maybe you've been This happens before, - right? - You come to the home page and what do you see? - Is he an image? - You see some colors Isam content. - And then you click What's to be clicked by a shoe and your forwarded to another page. - We can call that like the shoe page. - You come from the home page to the shoe page. - That's what you see. - You see the front end in your browser. - Any website is gonna always display in the browser. - But what really happens? - Well, - when you click on that shoe, - what's really happening is that that file is going to another back and file right. - This back and file is gonna have some back in language. - Maybe you'll be PHP or Ruby and that language talks to the database. - So this is the kind of flow we have will have in the front end something like HTML, - CSS and JavaScript. - Three languages working together, - which I only have one back and language. - We could say it's PHP in this case, - and we'll have one database that interacts. - And the storyline here might be something like, - Well, - I come to the store, - I'm gonna buy shoe and we come from that home page to the back end page, - That black page And that says, - Hey, - is ah, - is Chris a user? - And it looks in the database. - A database is just like an Excel filed its rows and columns. - And then it's like, - No, - Chris isn't a user. - And so it may say, - Hey, - okay, - well, - let's have him log in and then send him to this middle page. - This this cart recon shop out, - check out Another scenario might be back on the home page to the left, - Click the button. - I'm returning. - So now I go to that back in black page. - It looks for the database. - It looks for my name, - and it's like, - Yep, - he is a user let's send him directly to the cart. - He doesn't need the log in right. - So there's always this kind of, - like brain in the background, - this controller, - right, - that's that's deciding. - You know, - in this case it might just be one file like a literal file that's being red, - top to bottom, - and that's interacting with one database or maybe many many files. - But I think it's think it's easy to understand it with just being one file. - In some cases, - that's the truth. - So let's dive into the database what's happening in there with the data. - So in a database, - we have a bunch of tables. - Okay, - what's the table? - Well, - we may have a user's table, - for example, - and a user's table will be made up of something like the name right, - The user, - the password, - the email address. - You can see we have columns and rows. - It's much like an Excel spreadsheet, - like I said, - and you know, - for the user, - we may have a name like caustic right, - and then my password really secures. - Here. - Get 1234 and my email address, - right, - so each row represents a user. - Each column represents some attributes about that user. - Here's another example. - So we may have posts. - This could be a block post, - right? - And for the post, - Will may have things like in the row that first row we have. - Ah, - and I D c. - There's an i d for each one the eighties, - like the Social Security number for each for each line, - right? - It's just kind of like a number that never changes. - Right, - So we have in the rail, - we have a number, - right? - Let's get to the post state. - We have a date. - We have some content title, - right? - And let me have three block posts here, - and then we may have a table for comments right The way that you decide these tables. - Well, - this is part of the database schema, - and this is outside of the, - you know, - learning here. - But the idea is that we are putting into different tables these like objects where this - user's these posts were separating them. - These happen to be three tables that come with wordpress. - So just for example, - these air three tables you might see with wordpress and then how we join them together and - how we make them work together that's what shows us the you know, - the entire front, - the website, - the block. - Whatever it is, - we never see these distinguished tables. - Just one more thing, - another way that I think about these tables. - And again if you've never seen a database, - Uh, - but you've probably seen Excel A. - Databases like the Excel file itself right, - and that each of these tables, - if you've ever used the feature in Excel that you could make like a spreadsheet for each - page, - right, - you may have you, - me to your finances, - and that might be one file and then within their you may have one spreadsheet for you know - , - home, - another spreadsheet for work, - another spreadsheet for health or medical benefits or whatever you got in there. - But the idea is that you separate them into subjects, - but they're within this one file, - so we're separating our content into different tables. - But they're all part of one database and usually one database for a project. - Let's look a little bit more here. - We have the column for the users, - right? - This column is sometimes also known as the fields. - You can use either one when we describe a database and then we have the rose, - right? - And as I said, - each row represents in this case, - a user or may represent a block post. - It's one item, - right? - One record is another way. - We will call this our rows or records. - So here we have some vocabulary that you might want to write down. - We have again Fields and Records, - right users here, - right for all of our users we could do. - And this is some SQL code makes a select all from users where I d equals two, - and that's going to select all that Star Ming's all. - We're gonna grab that whole row there, - right? - So this is some X Q o code. - SQL is a language that used to query databases, - and it's agnostic. - It doesn't have to do with anyone language. - You can use Ruby and SQL, - PHP and SQL, - right? - Anything, - really, - um, - to interact with the database. - And in this case, - let's say we wanted to grab let me run to write some PHP code. - So in our file will write PHP and SQL code together. - And then when it executes it right, - so I'm clicking. - I'm on the front page of a website. - I'm clicking into a block post and this codes gonna read top to bottom and it's going to - say something like, - Hey, - go to the database and select post title No. - Two. - Bc post title Where is that right the right there. - Okay, - so select post title from posts. - What's Post Post is the table name? - Okay, - so select post title, - right, - That one. - That one column there from posts The So Table Where I d equals one so well on Lee. - Get that one bit of data. - Can you imagine what's what's going to spit out that one piece of data there from the row? - And there it goes, - comes back into you are Project. - So that's the interchange of their exchange that we have when we're writing code on the - back end and it's going back and forth, - we're using one back in language like PHP. - PHP works. - SQL write. - SQL again is particular to databases and General, - you could use it with my sequel database or post Grasser Oracle. - All these different databases will use SQL, - and then it comes back with data. - This is the exchange. - Let's look at an example of this in real life here So this is this is really what you would - see if you were to log into your database, - it's Ah, - PHP my admin, - which is just a view of our my sequel database. - Okay, - don't get caught up with the words. - Essentially, - this is a way that we can look into the database. - Well, - how did I get here? - Well, - quite simply, - if you were to sign up for hosting account with something like hosted Gator or Blue host or - any really hosting account, - um, - have it open here. - You would log into your control panel. - And so when you sign up, - you automatically get a U R L on a user name and password for this control panel, - and you would come down somewhere down here to our databases. - Here we go. - And all you have to do is click this button here, - and that's the database would open. - Now you need to create a database first. - It's just like two steps. - You would come into this screen first. - And if I just open this up here and we get this screen here, - you just basically put in a name for whatever database you'd want to dio call it whatever - you want to call it, - and you'd click create database. - It would take a second to chug for a second, - and you can see the database that I just created. - It shows up down here one final step that you need to do in this kind of messes People up - because they forget sometimes is you need to assign a user basically user name and password - to that, - and so you can create a new one here or I've already created one. - So I just need to assign that user by adding them by clicking this year. - That says, - Hey, - what privileges does this user having? - Unlike it's me, - man, - give me all the privileges Gold sweet, - good to go and we're good to go. - So you would come back when she set that up and just simply click on this year and it would - pop up with your database. - And so I've already done those steps, - but hopefully that grounds this in. - You know, - you could do this yourself if you were interested in going off and doing this, - have some tutorials on my blawg pf and p dot at me. - You can check out for setting that up, - but let's continue. - I mean, - I just think that grounds it enough in where this stuff is coming from. - I'm also using ma'am, - which is a local data base, - so that I don't need to be connected. - Teoh. - A server remote server. - So anyway, - but same same long story short. - This is the database. - This is the view. - What I've done is just installed a basic WordPress install. - So with WordPress, - you get 11 tables here for one site, - okay? - And so this is exactly what we were just looking at with the slides. - And you can see if I come into my posts, - right, - click into their and click on browse so I can see what's in there and we see exactly. - Yep. - Here we go. - We have the I DS, - right? - The post state. - So each one of these is one block post we get to the content of a blockbuster title. - Right is the new one. - Here's a new one here. - Each one of these is a block post. - And the columns each one of these attributes off that right. - And so exactly like we showed. - If we wanted to query some data from here, - we can go to this SQL tab. - It's going to allow us to write some data. - We can click on this. - I'll just delete this default to give us. - And let's type our own So you would do select Oh, - the star from the table. - It's the table name up posts, - right. - That's what we want to get data from. - And if I do that, - we'll see everything. - See exactly what we just saw there like, - we'll just show us everything. - We have everything. - When I get a specific piece of data, - we don't want to get all the data won't come to SQL here. - And then it's like this. - And this is where I waas here. - So select all from posts. - Where? - Where? - What? - Well, - let's just get one piece of data will get the i d. - Number one cool. - And so when I do, - I d number one. - Whatever the idea Number one is, - we get that there and you can see we have the post here. - I just wanted to get the title of this. - I can come here and edit. - This is a little annoying. - If you were to come back here, - it deletes the last thing you wrote, - you have to rewrite it. - But if you look at it So in this case, - instead of getting all I can just say, - I just want one piece of data. - I want the post title from posts and, - like, - click this and go. - And there you go. - It just grabs that one piece of data for me. - Okay? - With this query here. - Yeah. - So everyone to get just the most recent Blawg post, - we could say something like Select Blawg title is the block title from Posts An order by I - D in limit one. - Just show us one. - And now it will order by I d. - Well, - now it's still showing us the 1st 1 when we can do something like order by descending. - So show us the last one first. - And there you go. - That happens to be the last block words that was added to the site at the moment 3. Databases Part 2 [2:59]: - the important thing here just understand, - is that we have the back in language. - We have the SQL and it's talking to our database, - right? - It's giving it some kind of command. - Select that stuff for May and is coming back with some data, - right? - These in the languages we use, - this is the process we use. - And this will all make sense when we get to AP eyes because we'll see how it's actually - kind of fundamentally built on this premise. - And here's one more example. - So if we were actually going to this down here is the website, - right, - you can see that this is exactly what happened. - So on load, - when you load, - it looks that the back end code it goes, - Hey, - are there any new posts? - Looks in the database. - It says, - Hey, - send me the most recent posts sends back the data. - The back end goes, - Yep, - this is it. - Checks forests and outputs it to the front. - Right? - You only ever see that front end part, - but this is what is going on in the background. - These three parts talking together in closing will add there's only four statements or - commands. - You can make with SQL. - Every SQL query will start with one of these four words. - You can insert data into the database, - select data from the database. - That's like showing it. - Yeah, - you can update so I can take existing data and add something to it. - Or I can delete data. - Those are the four commands you can dio um, - act upon. - You could make longer things like select certain things or insert, - you know, - into one line or, - you know, - be more specific, - but these are the four general principles. - Okay, - I'm gonna make this unnecessarily complicated now and only because that's the way it is. - And I feel like I'm a journalist trying to report on this more s. - So bear with me, - this is true. - These of the four commands Sometimes they're also referred to as create, - read, - update and delete. - I mean, - the principle is the same. - It's just different words, - right? - So creating is the same, - is inserting reading the same selecting update and delete say the same. - So there's just different words, - you hear it's either insert, - select update, - delete. - That's actually what you type. - Um, - there's these other principles which working certain other languages right, - but create, - read, - update delete. - I bring this up because, - well, - you may also hear people refer to this as the crowd, - and that's what they mean. - Okay, - so the crowd is this idea of creating reading, - updating is leading. - It's the four things you can do to data, - and that's what it is. - Moving forward. - I'm gonna simplify this even Mawr and just say, - basically, - we're reading and writing data, - okay? - I mean, - that's the idea. - We're taking data from the database. - We're putting data into the database. - Yeah, - we could be deleting it. - Yeah, - we could be updating it, - but let's just keep it simple reading and writing. - But that's all the theory about how I got here and now you know the terms. - And if you're interested, - you can pick up an SQL book or learn a bit more about this terms. - But now we know where they come from. 4. APIs Read & Write Data [5:29]: - AP eyes read and write data. - So now that we've looked at databases and a little bit lower level kind of what's going on - underneath the hood, - let's come back to the higher level. - You know, - what can we do with AP eyes? - But we can read and write data. - What does that mean from the user's perspective? - Well, - we might come to a site like TechCrunch here and these buttons over here pretty familiar - with right pressing these kind of things. - Whenever you press one of these buttons, - they're liking something or Google, - plus ing it. - What you're doing is you are writing data. - OK, - you're writing data now. - Think about it on this interface here. - I'm pressing a button and it's going to some back end code and it's updating. - Let's say if I click the like button for Facebook, - it's updating Facebook's database with some data, - right? - So I'm just writing data from one interface, - the TechCrunch site. - Maybe your site. - Click the like button boom, - boom boom. - Facebook's database. - Updated writing data, - right? - What else can we do? - Well, - here, - you might think of this as reading data. - So now we're taking data from Facebook, - right? - And so this goes and it's select all friends, - right? - Sex, - all your friends from the user table in data in Facebook status. - And then it shows them here. - And so we could also think of an A p I as reading data reading, - data writing data. - Here's another example. - So here on the Huffington Post, - you can see the same thing. - Let's break it down a little bit, - step by step. - So here, - where season tweets and send me to tweets of people I follow. - So I show up on Huffington Post and I can see friends. - You know, - who I'm following on Twitter and things that they've tweeted related maybe to this article - or to The Huffington Post today. - And so that's what it's saying. - It's saying the code executes on the Huffington Post site and it says, - Hey, - go to Twitter and Twitter. - Send me to treats of people I follow. - Twitter responds. - It goes into the database. - That's a little search comes back and shows me a personalized message. - Okay, - cool. - Here is that data just personalized to my friends? - Here's an example of reading data, - and that would be the A P. - I call on the flow that it takes appear. - You see it writing data. - Okay, - so it's like, - Hey, - what do you want on tweet about? - Right? - What's your take on this? - And so I can write in some data here or something. - It's pre filled, - maybe, - and I click the tweet button. - And what's happening in the background? - Is there some code? - And it translates to, - you know, - post this on my Twitter at Castaic. - And, - of course, - because I'm logged in right and I have, - like, - a cookie or some kind of session. - That's what it's called. - It knows I'm logged in. - It was That's me. - And then that data is sent to Twitter, - which is really just writing to their database, - right whenever I update on the interface of the Huffington Post, - somewhere out there, - right and some server of Twitter is getting updated, - and that gets updated for every instance of Twitter that we have. - And sometimes we get a message back and you know, - the data will say, - like okay, - done. - And then we couldn't display that we want. - When we posted her, - things went well, - sometimes you want to read lots of data. - Okay, - so the two previous examples were, - you know, - nothing that you couldn't do just by going to facebook dot com or twitter dot com or - updating, - you know, - a status were liking something. - Just one instance of updating a single record in the database. - Well, - maybe we want to do a lot of things at once, - right? - Of many things in the database were read many things and put them together in some kind of - a really interesting way. - When we re lots of data, - this is sometimes referred to as a mashup. - Combining data are functionality from two or more sources. - So a mash up and these air popular, - you can google them and look on the web. - But any time you've ever seen data, - you know, - put on a Google map, - you know, - geographic data like this, - an infographic, - right? - You're taking data in this case from Craigslist and were plotting it. - So we're giving it a different interface or giving it a different look right? - Mash up. - Sometimes you want to write lots of data. - So maybe with one click, - I want to execute a handful of functions, - right? - I want to show my love for Nicolas Cage by clicking K's your Q and having every single - Nicolas Cage movie instantly moved to my cue and Netflix. - Awesome Marathon weekend. - Apparently things person thought so. - So this is what we can do here. - And ah, - you know, - this may be something that had taken, - I don't know this contain, - like, - an hour, - I guess, - arm or you make it distracted and start reading all the bios and get on Wikipedia and who - knows where this goes? - But all of that can be automated with a few lines of code, - right. - You write the code, - and we interface it with a button so that the user doesn't have to do anything more than - okayed your Q and instantly 49 movies. - That's the max 50 would be crazy. - Get added to the database. - And here's how that would look. - Of course, - Netflix has their own um you dev site for their a p I. - And so when you click that button, - some code is running over to Netflix and updating their database 5. APIs: XML & JSON [9:12]: - AP Eyes, - XML and Jason. - All right, - so let's go back. - Let's go back to the beginning of the Internet or what felt like the beginning of the - Internet 19 nineties right here is a well, - here is yahoo dot com When we went and logged on something like a, - well, - all of the users and they all stayed within a, - well, - all of the news, - right? - It was all kind of suspended within this what was called a walled garden. - You know the data. - It was like owned by a well, - and you couldn't get it out. - Same thing with Yahoo, - anything that was inside the Yahoo's site or within that domain, - there was no way to share it right. - There is no way there's no like social buttons. - There is no way to do anything that was outside of this walled garden. - One of the first popularized ways that data could leave a website was with RSS RSS got - really popular around 2000 for 2005 and it still is. - But around there you could go to a site like NPR, - write a new site, - CNN. - You would see these buttons. - They would look like this little orange button when you clicked on it. - You could then take that feed and subscribe so I could subscribe to you all the political - stories. - NPR described all the music stories and what do I mean by subscribe? - Well, - you know, - when you clicked on it, - you would get that in your Google reader, - right? - Or you would get that on your dashboard. - You could read in other places that weren't NPR, - or if you remember, - I Google was pretty popular back in the time. - I think people may still use it now, - and it was just like a place you put dashboard widgets so you could click on it and then - you would see that come here. - Well, - let's get through those steps. - What happens when we click on RSS? - If you know, - if I go to the NPR site and I dig around a little bit, - it's even on the home page. - You could click RSS, - and then you find all of the RSS feeds that have available these subscriptions. - We could click on music here, - and what do we get? - Let's take a look. - I'll make this little bigger. - We just get a bunch of data a bunch of data about the link to a certain story, - right? - The title of a story, - The date a story was published here. - This is a bunch of data and it's formatted in the language of XML. - You could see it says it appears, - XML, - um, - this is XML. - So what happens is when you click on the NPR site, - you're basically downloading or transmitting this file right and opening it in some other - service so that when this file updates so that with this file updates here, - I have linked to it and my i Google or my dashboard or Google Reader wherever I am, - subscribe to that. - This data will also update right. - But it's cool because I don't have to worry as a user, - and I have to go back to NPR, - right? - I can just come here. - This is my interface to that data, - right? - You can make these for everything can go to Craigslist, - and you could do a word search and say, - Hey, - if a bike for under $100 comes available, - making our assess for that, - subscribe to it and then view it here as a widget like it's as easy as that. - And in a way that's like a really simple A p I that were using. - And we're using the XML language for that. - So now, - by transmitting this data right or linking to it, - everyone, - I think about it. - We can have that data on the Huffington Post site here, - right, - and then make a link to it, - right? - Or a call on DSA send it to Twitter or receive it from Twitter is like a common language, - right? - It's Ah, - I think it is like the Esperon toe. - And could Wikipedia that was like the common language that was gonna bond all of the - languages English, - French, - Russian. - There's gonna be one language to unify everything. - Well, - in some ways, - we could say XML was sort of like this language that you could send it back and forth like - the Huffington Post could be written in ah, - against PHP or PERL. - It might be it could be written in PERL, - and then we could have the Twitter site, - which is written in Ruby, - right. - And the two of them can talk because they have this language, - this letter, - so to speak, - that you're sending back and forth when they speak back and forth. - We don't talk right to the database, - right? - We're not having the Huffington Post can have access to Twitter's database. - You know, - just is you building an app today can actually get into their database. - There's too much information in there. - It's like the bank fault, - right? - You could compromise their system. - You could take data. - That's not yours. - Direct messages. - That's from your neighbour. - Whoever. - Right. - So we have to put a layer in between there, - right, - A security away for security away. - Teoh rate limit you if you're taking too much data and shut you off And so we put this - middle layer and that's how this works here, - right? - And so instead of giving, - you know, - SQL directly to the database and direct access No, - no. - We put this middle layer here. - Well, - we'll send back. - Maybe XML or Jason will talk about in a 2nd 1 of these languages is common language that we - can send. - And then Twitter was the database, - and then they send it back to us in that data format of XML or Jason. - So what is Jason then? - And how is that different than XML? - What do we do with us? - Well, - Jason, - it's a lightweight data format, - and it's used by many AP eyes. - And so at this point, - I should, - you know, - make clear that Jason is the way of the future with a P I data formatting. - Right. - So we want to use Jason one possibles. - What all those words meant basically, - um XML It's fine. - We can still use XML, - but Jason tends to be the trend moving forward. - And so if you have the option or, - you know, - now you know they're both doing the same job. - But, - you know, - Jason is gonna be a little bit faster, - a little more lightweight and a little bit easier to read. - For most developers, - it's not Jason. - It's Jace on without the A and it stands for JavaScript object notation in the resource - files. - We have some XML and Jason files that have created just raw XML that we can look at. - Here is the XML example front, - NPR and just right into our browsers. - Now we could change things and highlight things just to see what's actually in here. - It's just data noticed. - There's no logic in here, - right? - It's not saying, - You know, - I can only access this if I'm a, - you know, - logged in user. - It's not letting me add up things in my car, - right? - There's no there's no like logic, - or if this or else that it's there's no credentials, - it's just data. - In a way, - it is just like a database. - You know, - Um, - I think of it. - You're probably familiar with CS V Files. - You know, - comma, - separated value, - CSP eyes, - what you use sometimes to export data from excel. - Right, - And you just go and you export it and then you couldn't import it. - Teoh another program or excel, - right? - Another Excel file. - Well, - that's exactly what XML as XML is kind of like that. - For your database, - you can export out as XML right, - or you could even export out of your database as CSP, - but is just one of those kind of common languages that weaken store everything into and - then bring somewhere else and import or do something with Let's take a look at another one - of these, - So here we have Jason Feet. - Now this is what Jason looks like. - Jason. - Some people think it looks a little uglier and you don't have that pink color, - but it's a lot born light weight than XML. - And let me show you what I mean. - Actually have an example of this which is Can you tell? - You know what it is? - It's my likes on Facebook. - Okay, - so you can see my name. - You could see my Facebook i d. - And some of likes the i. - D. - The created time and I have an example of this here which is in Jason that we're looking at - now. - But I also have an example of it in XML so side by side, - you can see how the XML I mean, - while it looks nice and pink in very cleanly tagged, - it's a little verbose tohave category category. - I d i d. - It's repetitive. - Where is this right? - It's a little more clearer. - And this notation also followers. - I mean, - this is little more high level, - but just more standard interfacing with javascript just easy to work with Java script. - It works nicely with a lot of languages, - whereas XML is just a little heavier. - So, - um, - overall, - we want to choose Jason, - and this is one of those reasons why, - uh, - actually you can't even get XML out of the Facebook A p I, - as we'll see in just a bit. - But I converted this just so you guys can take a look how it would look. - So look at this. - Look through it, - get familiar with it. - And in the next project, - we're going to work with parsing this, - which means making an interface for this doing something with it. 6. The Facebook API: Basics & Like Button [12:10]: - the Facebook FBI. - So you're gonna want to come to you. - Developers dot facebook dot com This is the developer site for Facebook, - and it will allow you to have access to the FBI and the data and a lot of other cool - features that the developers have access to. - To even get into this site. - You will need a Facebook account. - Okay, - so everything's kind of tied to your Facebook account. - Uh, - you could just sign in and you should see yourself up here if you don't review, - Obviously. - If you know, - faced with account, - just go set it up if you want to use this site. - Um, - when you get here, - this is cool. - This is a cool place to start. - If you want to see how other companies using Facebook, - you know what are their user conversions or return on investment? - There's some good stuff in there to just get an idea of creative ways to use the Facebook - FBI. - But I'm not gonna read through that. - We're not so interested in that today because we're developers, - right? - We're putting on our develop. - Perhaps we want to jump into the data, - and so I want to direct you up here and this. - These are the main features of how we can get started with the Facebook data. - The docks tab here. - This is where we'll spend most of our time. - We can learn about how to use the A P. - I will be code snippets, - tutorials, - all the good stuff news. - Um, - this is a great page because the team they're really dedicated to giving updates and - tutorials since the since they've started with the A p I. - And so you can look through the archives, - just get a sense of like, - you know, - what's deprecate ID. - Now what's coming up? - It's a really good place to get all this kind of updates and leave some feedback and the - APS so this will make more sense in a bit. - But the apse is where you're going to come to register your app. - Uh, - what we can do is we can look through all the docks. - I mean, - can play with the data. - But when it's time to deploy and go live, - this is really want to come and set up your app, - and it just kind of makes it official. - You get like a token and a secret and all this stuff. - So So let's come to the docks here. - Click on docks and you'll see right away that Facebook FBI. - There's a lot of complexity in here, - you know, - for whether you're developing for IOS or Android the Web, - there's many different options and how you might get started. - What we're interested in today is setting up some a P I calls via the Web. - What we can dig through here a little bit. - Got a core concepts under core concepts. - The first place I want to show you is the social plug ins. - This is the easiest way to get started. - Get your foot in the door and it's something you're very familiar with, - right? - The like button. - So if you're wondering, - how do I get a like button on my site? - You can click on the like button here on. - Do you know you'd reach the documentation that explain how it works? - Some of the best practices, - but right here. - Okay, - so this is the code that you can generate to make a like button, - and when you generate is code, - we simply put it into our site and you're making an A P I call in the background. - It it's so easy to set this up. - They want you to use their data, - of course, - that they want the like button to be and probably every single page in the entire Web. - And so they're being easy as possible. - They're going to generate the code for you. - Let's do that ourselves now and get our site set up with the like button. - To do this, - you'll need the resource files provided in the course. - Okay, - so here we have Facebook. - Basic face with basic is just gonna be a plain HTML file with some CSS and images, - right? - And if I just open this year, - there's nothing in here. - It's just CSS and HTML. - There you go. - No magic. - Let's take a look at the code. - Open up the code. - I could just drag this file to sublime, - and it's really there's just nothing in There is just some basic HTML. - Your 1st 10 minutes of HTML class, - you probably would have learned this here. - And so there we go. - Just have that there. - And so what we're gonna do is you want to grab some code and put it into our site now this - code won't run locally. - Right? - Locally meaning, - if you So I double click this file to open it in chrome or you kind of just dragged it to - chrome. - There's airways. - You can locally update things and view things. - We need to put this on a server. - Now. - We could use ma'am right? - The local server, - or we'll need to put it on. - Ah, - hosting that we set up if you're a bit confused. - Of what? - Those two things I said where Please refer to the set up. - Ah, - but the beginning and how to get hosting or map set up for this. - We actually can't even use local. - We need to put it. - We can't use map. - We need to actually put it on the internet. - It's the only way the Facebook like button will work. - So how are we gonna do that? - Well, - I've used FTP to get into my server, - right. - So my server here that I have set up with host Gator and I can just come and take this file - , - These files I gave you guys and we're just gonna upload them to the internet, - you could either take them from here, - right and dragged them. - That's one way to do it, - or I've also set it up over here. - So this mirrors. - This is what's on my computer and this is what's on the server over here. - So you could have just taken it here. - Dragged it over as well. - This is Transmit. - You may be using cyber duck or some other application, - but again, - all I'm doing is taking those local files, - dragging them onto the Internet. - And I set them up on my domain that I bought, - which is just the sub domain AP ice that seek a ST dot com. - And so now all I have to do is go to the browser to view that. - So I'm gonna go there and you can see this Index. - This is just saying, - Hey, - there's some files here you can get to and I'm gonna click on my folder and there you have - it reviewing that same file that was a second ago on my local on my desktop, - and now when viewing it. - But it's on the Internet. - It's at this address here, - and this will allow me to put a like button on this page and get up and running. - So what do I do? - Well, - let's come back to the depth site. - The first thing is gonna ask us is Hey, - where's the page? - You want to put the like button on and so I can just grab the U R l and paste it in there. - Let's see if it likes it. - I'm gonna think about it. - Looks pretty good not getting any errors, - so I'm just gonna press, - get code to grab the code. - Of course, - you could set some of these parameters. - If you want to change things, - make a different form or whatever, - but we'll just grab a code so you could get code. - And what do we see? - What we see Two steps here and honestly, - if you just read this, - it would be pretty easy, - I think pretty intuitive. - Um, - let me just highlight what needs to happen. - Essentially, - we need to take this code here. - This is what they're calling the sdk, - right? - That's going to allow us. - It's kind of like the library that's going to allow us to do anything with the Facebook ap - I So we just have to include this once into our project and as they tell us. - I mean, - to put it right after the opening body tag. - So that's some pretty basic HTML stuff right there After the opening body tag, - some was pasting it in right there. - Right, - This whole bit Just get out in denting clean it up, - and there we go. - That's step one. - And now the second thing they're telling us is this bit of code here. - No place this where we want the plug into appear. - So wherever I want that, - like, - button to show up now that we're gonna put that code there. - So maybe I want to hear underneath my title, - have a like button. - That's it. - So once I do this, - I can save my code, - right? - I just added the two snippets and upload it to my server. - I don't need to upload everything again the CSS and the images. - Although you could I'm just gonna grab this one index file. - The only place we made the update and transmits going to say, - Hey, - do you want to replace that? - And I'm like, - Yeah, - and so now I'm just gonna come to that address again where I have it here and whenever - fresh boom, - there it is. - We got a like button, - and if you like it right will pop up. - What? - You send a message if you want, - and hopefully my photo will show up for a fresh. - There you go. - If you are this far, - you might want to check your Facebook and unlike it, - so your friends, - unless you want to show them. - But that's what's happening. - That's probably sending that to your newsfeed right about now. - You could also unlike it like that. - And so there we go. - We have a like button set up in our page. - It's pretty easy if you curious what these other options are. - These are just some older ways to do it with the XF b M L. - I frame and you are l but won't want to do with the HTML five way. - This is just the you know, - the best way to do it. - So there we go. - So that's a simple AP I call and these social plug ins that they provide. - There's a lot of really good ones that you can get some super like seemingly powerful ah - functionality in your sight. - But just a few clicks. - So comments, - for example, - is pretty sweet If you want a commenting system, - right? - A threaded commenting system on your site. - Well, - you can click on this social plug in for comments, - and it's the same routine here. - We just need to tell it where we gonna put this, - and I'm gonna put it on that same mural. - Of course you're gonna put yours wherever you're hosting it on the server. - We could set the with number of posts if we want all this, - But we're just gonna grab the code again. - We want the HTML five version. - Now, - We don't need this library again, - because this is, - you know, - we've already done that again. - This is like the injection of were connected to Facebook, - right? - We're bringing in that connection, - but this is all we're gonna need forever. - We want a place, - the comment system. - So I'm gonna grab that and come back to my project. - And let's say we had an H two here and I could just make any chooses comments. - That's just some HTML and I can pace that code. - There we go. - And now I'm just gonna updates filed by dragging and dropping it on the server. - Yep. - I want to replace what's there? - Come back to our projects very fresh. - And there you have it. - We have a comment system as well. - So now you could write a comment pretty cool. 7. The Facebook API: The Graph API [9:24]: - next. - We want to look at the graph a p I. - That's going to be under a p I reference and graph a p i the graph AP I It's like the core - of the Facebook FBI. - There's a lot of data here in the graph FBI and so we can look here and click on graph FBI - to enter. - And we'll see a lot of details here and how to get started and what kind of information we - have access to things like the albums the friends links, - messages, - tons of stuff in here that we could grab. - But hold on, - let me let me back up a second and I'm gonna give you guys some code that I got just from - this page here just on how to get started with the simplest AP I call using the graph a p I - , - and this will help us see it in action and make some sense of it. - What you're gonna want to do is look at the Facebook me example I've given you that's gonna - be under Facebook. - It's with me this year and let's upload this story server and see what happens. - Minute, - come back and put it in the root here. - And then we have Facebook. - Me and so I just uploaded it. - They're just drag and drop it there. - So now I have Facebook, - me and all of those files on my server. - You may have noticed how I changed from dot html in the last example to dot PHP. - And that's because we're gonna be writing some PHP code in there. - Let's take a look first. - What's going on? - Well, - if you come to your server and you refresh well, - you should see something like this and I'm gonna click on Facebook. - Me and you should probably see my name showing up, - right, - just like this year. - So it's the template that I gave you as the html CSS template. - No magic there and then just this name here. - Now this name this is coming from the Facebook database. - This is an A P. - I call. - Let's look at how I did that. - We can open up the index that PHP file in sublime by dragging it or I just or I just did - command. - Oh, - and I've written the code for this example so that we can see what happened without Evan. - Actually do any code in this round. - So here to here we have the basic PHP call, - right? - Everything else is just some HTML, - but because the stock is called dot PHP were allowed to put into PHP code here. - And so I put some in. - And what did I do? - Well, - I made a really basic call to the FBI. - Here. - See this girl here? - Why don't we take this and put it in the browser and see what's there? - Okay, - there we go. - What is this? - What kind of code is this? - Do you guys remember? - It's maybe XML or Jason, - right? - This is some Jace. - Um, - if you can recall with the curly braces Yeah. - Is this, - um, - Jason code that you can get from the graph a p I And this is the only public data that - Facebook's made available. - Then you can come here and you can put in your own handle, - right? - Your vanity name or whatever it is or your number even says my Facebook number. - That would work the same if you put your number and you'll get this public data. - And so now we can take this Jason feed and that you are well comes into our project. - And so here we have the URL. - And what are we doing with this? - You're l? - Well, - we can use this function here, - right? - So there's this function in PHP and you can see it once looked like this. - And so anything that I put between this and the two parentheses, - it's going to grab that Web page, - right? - It's gonna grab what's on that webpage. - The code. - Well, - what's on that page? - We know there's that Jason Data. - So that's exactly what it's doing. - It's taking that Jason Data pulling it into our project, - and specifically, - we're assigning it to a variable here. - Right. - So we're kind of just like putting into this little word of this bucket so that all of that - data is now accessible through this one word here. - This next step here, - This is just a standard step. - We need to put it in the function. - J. - Sandy code. - Right. - So again, - we're just putting this here into this year. - You just need to go through this step here to decode the Jason. - And now we have the output and we are good to go. - So those the two steps, - we pull it in, - Put into a variable to code the Jason. - This stuff here, - This line down here. - Echo. - Remember, - Echo prints out what we have is gonna print out our name, - but that's not gonna make maybe so much sense right now. - I want to, - um, - look at where I got that from. - So these lines here, - this is where he contests to see the output, - Basically, - to just check. - You know, - is this stuff coming incorrectly? - And if it's coming incorrectly, - Well, - what's the data that were pulling in? - So I can uncommon this right? - So you'll notice there's the's great out pieces of code. - This is commented code. - It doesn't get executed while it's gray. - Um, - there's two different ways to do it. - We have this block one here, - Right? - This one here. - You see, - if I remove that now we're have this exit units would work, - but that's not even code. - So that would error. - But so we just want to get rid of these and we can try if we can comment these out here - like this. - Well, - now this PHP code that I've written this will run right from top to bottom it's gonna read - through here. - And this is just some testing that you can dio The powerful thing here is this print are - Let me show you what it does. - So I'm gonna save this. - Come back uploaded to your server, - refresh and we refresh that print art took that variable tick wallet data and now it's - displaying it here on our page. - Right? - And so exactly all of this here that's on Facebook site we contest in, - say, - Oh, - actually, - that's coming out here on our site, - right? - So again, - we pulled in the data. - That was the first step. - And then we're just testing and we're saying, - OK, - everything's here. - And now that third step is just taking what we want and bringing that specific piece of - data into our project. - And so, - you know, - I just wanted the dame rights name here, - so I grabbed it. - Well, - how did I do that? - Well, - the way we grab the name was we take the graph Alp variable. - Remember, - everything's in here right now, - and then we just dig through it a little bit and so we go. - This is the symbol to go through an object and we went taking everything into consideration - . - I want the name right and let's look that looks like again. - So here's everything and I want the name. - So I just take what I want. - All right. - If I wanted the gender, - I couldn't comment. - This year, - you'll see we'll grab the gender right And if I wanted the This one's a little tricky into - this, - but this will take your I D and pull your image based on the i d. - So let's see if we grab a name. - We did that one. - Let's grab the gender and the I D to make this image and let's see what happens now when - they're fresh. - There you go. - So now I'm just pulling out the name, - the gender, - right, - And the photo there. - And if I do a control view page source well, - what's actually happening into the hood? - We'll notice. - Of course, - none of the PHP is printing out, - but the output code is right. - The, - uh this is by testing and my name right, - and the image says that image. - And you can see this the link that I created this graph dot facebook dot com image right - Click on it will bring me to that image on Facebook's page. - There you go. - I am. - And there you have it. - No, - I So I can get rid of my testing here. - I don't need that anymore. - And we can have our page that we made. - Also, - if you were looking at the testing code, - there were some things that pre opening close that just kind of formats. - This in a nice way view. - If you were to remove this, - it would still work. - This one and this one. - This is the powerful line that lets you do the testing. - But this just kind of formats it the pre formatting. - So yes, - all together we have that and we're pulling in some data into our project. 8. The Facebook API: The Graph Explorer [29:02]: - the next project I want to work on with the graph a p I is getting into the photos by photo - albums and Facebook and pulling that data into our project. - Let's say we had ah, - blawg or, - you know, - some kind of profile that we want to take some of our photos mean we're making a photo - gallery, - and we wanted the latest updated photos from Facebook to you also update on our home page. - Right? - That'd be pretty cool. - So how do we get access to that data and then pull it into our own project? - Well, - we want to start with a graph a p I. - And I'm not sure you an easier way to look through the documentation of the graph a p I. - We can click on tools here. - And the first option here is the graph ap I explorer, - the graph FBI Explorer, - if we click into it, - will allow us to funnel through the data in the graph FBI. - So we can see basically hate. - What data can I get out of here like how much is in here and how do I query it? - Let me show you what I mean. - So the thing we just did the most basic is just taking your name here, - our number, - right? - And querying that data. - And we had at first what we had, - if you remember, - was just was just this bit of public data. - Now, - of course, - information on Facebook is private, - right? - Most everything except for this little bit here. - You know, - my list of friends my list likes, - you know, - all that kind of stuff. - I don't want everyone having access to that data, - right? - Just as if I'm not like friends with you on Facebook, - I can't even see most of your photos, - right? - Right now, - like with the human interface with me clicking around. - And so the same goes with the data. - I don't have permission to get that stuff. - Let's come back to the graph Explorer. - But what we can do is we can get permission for that. - And what that's going to be called is this access token, - right? - And the access token is like a password or some permissions that we have. - We've been granted so that when we use this token with our code will be able to get more - than just the public data you dig into the good stuff? - All right, - So how do we start using this? - Well, - let's find some data that we want to use the graph. - Explorer, - will, - you can simply come and just start playing around the Jason code here and zooming through - it. - And you can also come over here to the left and take around a little bit. - You see, - if I click here, - I'll be able to get all of the information. - First name. - Just get the first name. - Let's say we wanted music. - What? - We can come down here and click on music. - You have to click the submit button after we make requests, - and it will bring us back the data. - And so then here we get the Jason feeds. - This here would be the entire bit of code. - Everything that you've ever liked, - that acid it with music. - You get that whole Jason feed and it comes in a you Earl, - which is gonna be right here. - This is gonna be the new your l we need. - And this your l if you click that there, - you actually see the full your l That's what that ISS and then they're just abbreviating it - there. - But we can get this full your l receiving Grab that and bring that into our project. - But now we can't just come and go to the browser like we did before this year. - Right? - Because if I append that on here and I we're gonna get an error, - it's gonna say error access token is required to request this resource. - So what? - That sayings. - Yeah, - basically, - I don't have permission to get this stuff. - Well, - what we can do is we can use this access. - Took it. - So they're granting us an access token. - Um, - this one they're giving us here, - it's temporary. - I think it lasts for about an hour, - but we can use it. - Let's just see what it does first, - So I'm gonna copy it. - You want to come here and append to the end of the URL and access underscore? - Token Equals says that the party added here and access underscore token equals and then - paste in that access token. - And now if I return There you go. - So now have access to all that data, - just as it did with the first example. - Right. - So back here, - you can see we have our access token when we click this year could get access talking. - You'll see the access we have now. - You may or may not have some of these checked, - but if you want access to birthday or to the likes, - right, - you have to actually check this and then get an access token and you're getting a special - token it wants me to do this year. - You may have to log in again, - are verify it. - But I've already clicked all mine, - So unlimited access, - which is kind of cool in your testing, - right When you're testing, - you could play around the token that has unlimited access. - When we go live, - you may want to limit it and just have just likes or just the events with one thing you - need because what you're going to see and this is going to the future a little bit right of - deploying it. - But what you'll see is I'm gonna come on. - And if I'm a random user, - it's gonna say, - Hey, - I want to access your likes. - But if you're asking for everything your likes, - your friends, - your friends of friends, - your photos, - I'm gonna as a user of you like Why do you need so much information? - You know the site if it's Huffington Post, - er whatever, - blawg. - Um And so that's where that's where these permissions come in. - When we're testing, - we can take everything because we just want to see what we can get. - But then we probably want a parrot down when it's time to launch that we don't, - you know, - intimidate our user and be like a or taking everything from you. - And so there you go, - there we have it and we have access to our data. - Well, - what I want to do now is I'm not gonna take music. - I'm gonna take Get rid of these here. - I'm gonna take some vote photos. - Me going to the photo album. - See how we do that. - If I click here, - you can look for photos, - Photos down here. - Click on that. - Remember, - we need to resubmit it. - There it goes and cool. - Now we have the photo data, - the I D. - Which is my i d and each of the photos. - You notice that for one photo, - we have various sizes to its storing different sizes of that one photo. - So we're going to get into this in a second before I go to that, - let's see what's going on here. - Notice how I'm a pending anything after this question mark. - It's becomes little variables. - And so I'm saying we're field equals photos, - right? - And so what that's doing is it's going and looking for the table in the database where it - can pull all that data about just about photos. - And so we're getting specific. - Remember when we just had this? - It was either the public or the front facing data, - but now we're like, - specifically drilling in. - You don't have to worry too much about writing this by hand. - It's just kind of good to know what it's doing. - That's why this Explorer it helps make thes queries for us. - And then all we have to do is take this girl right now. - I'm gonna take this your own bringing into my code, - and we'll do it by scratch this time. - So we're taking your HTML. - This is just the index html that we had, - right index, - that PHP that I created. - So we have this index that PHP and I'm saying, - Hey, - I'm gonna write some PHP inside of the HTML. - It's here And what PHP do I want to write? - Well, - the first thing I'm gonna do and its plot this out with some comments men, - if all the same procedure as they did in the last example. - The first thing I'm gonna dio is I want to get the data. - The second thing will need to Dio is a test of the data. - You need to do that, - but helpful. - And finally, - we will print out the results. - So I like to put my comments and steps, - so I know that, - you know, - in English these are the three things I need to do logically, - and it makes it easier. - I could just go through now and kind of translate that into the PHP language. - So get the data from Facebook. - Well, - we know where the girl is. - We have that. - And we have the code from the last example cause I should yet to do it. - And so you could pause here and you look back at that and take this upon yourself if you - want to play with it. - But let's go through. - I'll do it right now. - So we need to take that you, - Earl, - we need to take that. - You are l using the function file file. - Get contents and you could see sublime. - Help me out. - It's like a what file do you want to get? - And the final I want to get is going to be at a URL, - right? - It's gonna be a that Facebook, - your all. - Not that That's not the whole thing. - So we need to go back to the graph. - Explorer. - What was it again? - OK, - it's graphed out facebook dot com with all this stuff right, - Furthermore, - unity this access token in the 2nd 1 was gonna grab it now. - So graft at facebook dot com With that, - there we go. - Looks pretty good. - And remember, - I always need to upend my access token and access token equals There you go. - And I always need to end everything I do in PHP with this semicolon ends the line. - So I'm taking all of this content an ominous sign it to a variable. - Of course, - I can call this very well anything I want, - but I call it the graph. - You are l which makes sense and I need to take all of that Jason we're taking and I need to - decode it, - decode it so that I can use it in my PHP. - Project groups want to use a variable. - So he's the dollar sign and the line with semicolon so that it knows the lines finish. - And then I can make a new variable to put this into. - There we go. - There's there are steps. - So all of this goes into their now. - I could do stuff with that. - And I'm doing What am I doing with them decoding it? - And that decoding happens. - And now it's in this word here. - So we're just going step by step, - kind of knocking it around. - And now we want to use that graph output. - And so we contest. - Let's test to make sure that graph out but worked properly. - So these prints are this print our function, - and I'll just put graph up in there and and line we're done. - This looks pretty good. - So I'm saving this and uploading it to the server I need to do is take it from your local - right. - So this template file upload it here. - And when I come to the site now I can see you Facebook photos click on that, - and I haven't error has failed. - Open stream. - Http. - Request up. - Okay, - so, - you know, - sometimes this will happen. - It's pretty normal when you're developing stuff that you're gonna have an error come up and - generally and PHP the errors are somewhat friendly. - Like they're trying to help you. - They're gonna tell you like the line that era razon or try to describe best they can. - What was up? - Um, - it may be that this is Http s. - That would be my guests, - and I just copied it wrong. - So let's take a look at the explorers. - I look at that wrong, - and yet you could see, - Actually, - it needs to be HD to be s, - which kind of makes sense. - So if you come back to your code, - right? - And we were just at the s here. - Http s save it and upload it. - Now, - when I come back to my projects and I refresh Okay. - Cool. - There. - We got it. - All the data is test. - Everything's working. - That is a lot of data. - Whoa. - Okay, - cool. - It's all coming into my project. - That looks good. - Another way that I could have tested that https thing was to just put that whole earl up in - the browser and see if it was working here. - You can see that when I take the s away here. - This is the error I was getting. - So this is a good way to Testa's well, - with the S. - It works perfect. - Very cool. - So now I have all the data in my project, - and this looks kind of messy, - so we can clean that up a little bit if you remember. - In the first example, - I cited that if you put these pre tags around the test formats it for you and so open and - close in the line, - save it back and refresh very ghetto. - And if you're wondering I'm working off the server with that PHP file. - I would recommend that you just uploaded each time and drag and drop it. - Um, - you know, - take your time with this pause and do what you have to dio. - I'm just doing that for speed sakes, - you know, - watch me. - But every time but in what I'm basically doing is in transmit. - You can just go here and just open file with It's not really the best way to definitely - wouldn't recommend it on the production for a client or anything. - But if you're just playing around and ah, - you know, - trying the Lord and I think it's fine. - So that's alleged there. - And now we can see the same data that that mess of data that was pouring down the page, - but it's organized a little bit better. - So now I can read it. - And, - baby, - it still looks a bit scary. - But I mean, - look, - it's fairly to it. - If we read through it, - there's an I D of the number. - Then there's something called photos objects. - Something called a ray of this could get a little scary. - Well, - let me show you how to read through this and get what we want. - You know, - first, - my eye goes to you. - Well, - what do I want? - Well, - I don't know, - man. - So many things. - Um, - what if we were to just take one of these images, - right? - Some of this data and open it. - I mean, - I think it be cool if we could show some of the images that I want. - The source. - It's the width and height for that. - I don't want a smaller image. - Maybe I'll take a smaller image I'll take this. - This one down here, - this one that's to 40 by 3 20 Right. - These air, - actually, - all the same image. - I mean, - I know that already, - but you could just test them by copying that link and pasting into the browser. - There you go. - You can see that there. - All right. - And you would see it if I were to grab a different one. - There you go. - This one there looking pretty good. - Um, - cool. - So if I wanted to bring these into my projects right, - you could pick the size. - You want whatever one you want. - And now that I know the data that I want now, - you just have to find how do I go down this tree to grab that data? - Well, - let's start here. - I need something called source and we just work our way back. - Source six. - That's inside of images. - Images is inside of zero data. - This gets a little bit confusing. - I'm not gonna lie. - This takes a little while, - but the idea here, - the concept is that I have to kind of dig through this tree, - right to find that piece of data I want. - And so let me show you how this might look. - Let's start at the top and go back down. - So at the top, - let's just say we wanted to get the I d will start something simple to get the i d. - All I need to dio take that output and say I want the I D. - That one's pretty easy. - Let's save it and take a look at what we got. - So if it dragged down to the page, - all the bottom quote that see a day So I'm pulling that piece out right? - And I printed that out of the bottom. - Looks like it's part of everything, - but I printed it out their Colson. - Now we know that. - That's how you get the idea. - That's pretty easy. - I just said Pointed to I D. - Well, - if you want to go one level deeper, - what if we wanted to get the i d for the photo or the photo name of the person that - uploaded it? - So for that, - and this is gonna be a little tricky when you do an object. - So I had an object. - We use that arrow that I just use the arrow i d. - But now I need to go these air on the same level. - I need to go one level deeper into the array, - and it's gonna look a little bit different. - I'm needs these brackets, - so I'm gonna do I d data zero array and then arrow I d. - That's an object to a narrow name. - So let me just do that and we'll see how it works. - See if I remember. - So what? - I said there was a need to say, - Just tried a different line. - Graph output. - That's what it's called. - I need to go to you. - Was that again? - Photos data zero. - So photos is an object, - and then data zero it said array. - So it looks like that with these break its brackets here and then once I'm there, - I need to go into I d. - I know I need to go into from name, - and that's an object object. - So it follows this index year from name. - All right, - so if this works, - I should be printing out the i d. - I'm gonna comment this out. - We don't need that anymore. - So it should be printing out the person's name that uploaded that photo of me. - So got that. - We're saving it. - And when you refresh and I come down to the bottom of the page yeah, - we grabbed it. - We grab the name. - Where? - There. - There you go. - Looks pretty good. - And, - ah, - you know I can I can put some if I want to put like an H two before they're each three and - then after their this will just put some HTML tags around it so that we can see it's - different and we can see. - So basically, - this is just some HTML on putting an HTML open and close. - And then anything between there's that data. - Let's take a look. - So I'm saving this. - And so now we won't actually get that photo right. - So instead of going into from, - I want to go into images, - noted a sounds on the same line. - So I want images. - And then which one did we want? - We want the smaller one. - So images. - Let's say this one here, - we'll get five. - So images. - Five source. - That's where that lies. - So let's see if we can grab that. - So instead of from its images images five, - remember? - Was it a ray and it was five source like that, - so that should be the full. - See if it works. - There you go. - So now we have that you are well, - so I'm pulling that your URL into my project. - Right? - That director where? - L and that's really powerful. - Because what can I do with that? - Of course I can put it in image tags. - Let's take a look. - And so now that we have that direct reference to the image, - this is that image link, - right? - Well, - now I can just use some HTML to print out the image ends. - What would that look like? - Well, - they might just wrap an image tag and sort of image source just like an HTML. - And then here I want Teoh, - and this is a little bit advanced. - But what I'm doing is I'm just as I would write some normal html amazing print out some - HTML and then join this image as the image that would be like the reference to it. - Then we need to end this here like this. - So let's take a look and see if that worked. - And there you go get the photo down there. - Cool. - So now we come back our code. - Just explain again. - We have this image tag, - This opening image tack. - And what we're doing is we're just where you would put the image, - right. - We're just putting this, - which represents the image that these join it. - Right? - So if you've ever used java skirt before, - use a plus here. - We're using PHP s dots, - and this is escaping. - So what this means is, - well, - you need to have a this ah, - double quote here, - just in html. - And if you put that there ends, - if you had one, - it would end. - And so we need to have this here escaping. - It kind of allows it to print out if I view source. - All right, - So they escaped one prints, - outs, - and then I can see it there. - Right, - cause it needs to be there on both sides. - Ah, - and it doesn't get ready, - is PHP. - It just knows how you put that back slash before it. - I actually want to see that when it prints out in the code. - So that's this piece right here. - And then this ends, - joins us. - A little works cool. - So now we have one image, - and ah, - I don't think we need to test anymore. - I can comment this out here. - I just did command question Mark my browser and the comments at all that. - So I won't see that testing good and everyone to point out multiple images. - Um, - all they would do is take this line here and just copy it twice. - Really? - Right. - And I could put a b r at the end here if I want to just separate these, - right? - So just break the line so they don't sit next to each other. - And this would be the same image twice. - But if I wanted to go through to a different image, - I can just go to one writes, - I'm just going down that tree. - Come back here. - I fresh. - She had two photos. - And so now if I add another one here rates at a second photo and 1/3 photo and I'm just put - on these be ours to break the line after each time. - Now I'll put out the three most recent photos from that list of photos. - And when we come back to the site and refresh Lario, - you see three photos, - some weird stuff that's coming from my timeline. - I think Christmas pyramid here. - Great. - Uh, - And so that's how that works. - Um, - those numbers here are each of the numbers. - And remember, - we're just reading that from the Jason. - These were the sizes you remember. - So it kind of makes sense that if you want to make them smaller, - we could probably choose a smaller. - Remember, - they were going incrementally. - Those would shrink, - and we could even make them something like eight Weaken. - Go back to the testing if you wanted to see, - I think eight is option for a very small photo. - Let's undo the testing and come back and see if it works. - And we're just 80234567 eight yet but the smallest size er here, - So eight would be 97 by 1 30 And if you go to the bottom of the page, - you can see Yes, - they all came in like that. - So that's what we're doing here. - We're reading these, - uh, - these objects in these arrays. - That's what this is. - And it's it's all part of the Jason that is being brought into our project. - So finally, - I'm just gonna top this off. - This is getting a little advanced here, - but you should get a sense for, - like, - what's possible. - But it's You may notice that, - like these numbers like this is a little inefficient because, - I don't know, - hard coating these. - And I'm repeating the same thing. - Three lines. - So what we could do is we could loop through so that we could just put one line and have a - loop. - It just says, - Well, - now it zero the next time it's one of the next time, - it's too. - Can you imagine? - Right? - So I just have this one line here, - right? - So get rid of these here. - And what if we wrote a little loop so that it changed right incrementally and that would be - pretty nice. - It would be less co two be easier to manage and what that's gonna look like. - It's gonna be a four loop, - and this is just ah, - you know, - a standard coding concept. - It's in many concepts, - and it's gonna look like four, - right? - It's gonna write it all out. - Oh, - I know I know what you're thinking. - It's horrible. - It's standard and really what it's saying if you just kind of copied it, - you just have it in here saying, - um, - I this thing I'm making up. - I was variable, - I whatever that is and call whatever I zero as long as zero is less than five do this thing - . - And so each time will go through and make it one more. - So it would be like I plus plus +0123 and increment. - So if I put this number and here in place of zero the first time this I will be zero, - it'll go again. - Plus plus will be +12345 stop, - Right as long as it's less than five. - So it's gonna print out five times five images and then it's going to stop because I'm - saying less than five. - And so we do this correct. - Come back here. - And so I'm gonna undo Undo this. - Commenting here. - We don't need the comments, - the testing anymore. - Just want the five images gonna refresh. - And there you go. - So now we have our five images printing out. - That's pretty sweet, - little blawg. - And again, - this would update in real time if I would add more photos to my timeline. - Right. - And we're going from zero photo to the five photo. - You could even go back in time and say something like Started number 10 and then go through - 10 to 15 whenever you have flexibility there. - But that's essentially what you're doing. - You're in commending this number and that increments here, - and you can have some fun with that. - So this is our example of photos. - And Ah, - please look through that and look through the graphic spore and have some fun. 9. Facebook: Recap & Beyond [3:44]: - There are a ton of other options and features available in the A P. - I so weaken keeping into the graph a B I or you can click around the docks a little bit - more and you may come across Facebook. - Query language, - SQL and F UL. - It's pretty much the same as the graph a p I and you know ad price. - Start with a graph a B I. - But SQL allows you to do just a few more. - There's a few more things you can't do with the graph api I, - but you can get access to with F u L. - And the nice thing about EFC ul is it's very similar to SQL right, - which many people are familiar with, - so that you can query the database and, - well, - what's going on here. - You can see Yes, - you're basically writing statements just like SQL Select name from user so that you can get - that kind of data and they give you a lot of examples here. - We couldn't click around a bit under the FBI references and find all of the tables that we - have access to in Facebook's database and all of the common and all of the columns to so - for the photos table. - And you can see the columns. - We have what each one is doing. - And of course, - of course, - this isn't SQL right? - Were no have total control, - but F g well, - they're limiting in some ways, - but this is what we have access to. - Digging further into the FBI. - You may see the open graph the open graph that I don't know why it sounds so much like the - social graph. - It's pretty confusing, - but, - um, - open graph what this is This allows you if you want to go beyond a like button and you've - seen this before, - I can say, - Hey, - Chris cooked something right or Spotify is really popular when you see it's like someone - listen to a song on Spotify So this allows you to use extra verbs and that kind of stuff, - the actions and objects is what they call it here. - So if you're interested in that, - you may want to learn more about using the open graph. - And when you're finally ready to put your thing live on the Internet, - remember the access codes we've been using? - They're just kind of basic, - but you're going to need to get familiar with the sdk for PHP if you're gonna use PHP and - this will show you how to set up your I d in your secret, - the permanent ones and get users to your site. - It's a bit more complicated than just this. - You'd have to read through the documentation, - but essentially, - you're putting this on your site. - Someone can either Facebook connect right and connect into your site. - Or you can get in access to come from some other way from your user. - But that person has to authenticate you on their site. - You'll also need to get the app I D and Secret, - right? - These things, - Um, - And by doing that, - and to do that, - you need to go to APS here and absolute value to register your domain. - And so you would click on, - create new app and you put in your app, - name, - name, - space, - and what they'll do is they'll set you up with this here. - You don't need to fill out a few more things that will prompt to you as faras your l in - your name and authenticate it and stuff. - But it only takes a few minutes to get set up and you get your own app, - key and your secret and using that with the sdk. - Putting this on your server reading through this, - you should be able to get up and going with the face with the FBI and throw it live up - until here, - you could just do the like button. - Remember the like button. - It makes it so easy. - You don't even need to authenticate your user. - It just does it kind of automatically for you. 10. The Twilio API [12:08]: - able Now we're gonna look at the twilio AP I twilio is pretty cool. - They allow software developers to programmatically write some code that interacts with a - phone or an SMS, - right? - What that means is I can write some code that makes your phone ring right. - Or when you call me, - you can leave a message, - and I can put it in my database or do something with it. - Right? - Um, - you know, - typically, - you would rely on a big, - you know, - big system in the past, - like cisco or something. - Teoh set up Ah, - calling. - You know, - press one for this option. - Press two for this option. - This whole, - this whole thing of routing actually, - no idea that works, - But I do know twilio works. - It's super easy. - Um, - you can get started just by signing up for an account and writing some PHP code. - And that's what we're gonna dio. - It's pretty great. - And so what you see here is we're going to write some goat and it's gonna you know, - we're gonna help get up to you twilio, - and then we'll have the phone interact with it and magically, - things will happen. - So to get started with twilio. - We need to comment to you twilio dot com and we're going to sign up for an account. - We can come over here and click on the log in button. - Don't click on the register now. - It's a little bit of a bad ux. - Some people click on that and register for the seminar. - What we're gonna do is actually log in and get an account. - So we log in here and of course, - we may not have an account yet, - but we can sign up for free. - All right, - great. - So we just want to put in her name here and get started. - Well, - the first thing they're gonna ask you to do is just Do you verify that your riel? - And so you just need to throw in your phone number here and click text me Just go through - the next few steps, - getting set up. - Twilio sent me an SMS. - I put in the verification, - just go through that little step, - and now they will assign you. - Ah, - phone number. - Right. - So this is my phone number, - right? - That I can use for my only for my account of the giving me here. - Um, - and you could choose your own if you want and get a different get a different phone number - . - Area code. - Gonna fall of flexibility. - Once you do a paint account, - you could even get an 800 number, - which might be cool for your business. - But we're just gonna stick with this one that they're giving me, - and I'm gonna get started. - Giulio really wants to make this easy for you right now. - They're showing you that you can just send an SMS, - make a call, - receive a call. - You can do all this basic stuff right here without even writing a line of code. - So if I want to send myself a message, - send SMS. - Yeah, - I just heard it go. - Um, - and so it send me that sms to my phone number, - and now they're kind of walking you through the steps. - They're like, - this would be the code to execute that. - This is some curl you could execute via your code if you wanted to. - Um and they would do the same for each of these here. - But let's go into the account, - and we're gonna walk through reading some of the code ourselves when you get in here. - We have a trial account, - right, - And they're telling us you have a trial account. - You could use it pretty much as much as you want, - you know, - But you're going to get this message when we if you call, - if you use that number, - it's gonna say you're using a trial account. - And so that's basically how this works. - Um, - you can put $20 into your account. - This would be removed. - That message would be removed on You could just upgrade if you want, - but we're fine. - Just using the trial account we can get to see you know just how things are working. - Do a few things Note here. - Um, - we have this account s i D. - Which is going to be our account secret I d. - And we have this account token. - If you click this here, - you'll get the token. - It will appear that they're right. - So these were going to be kind of like our passwords, - right? - The s i d. - The secret and the token. - Those are data that we can pass with our request. - So that were like, - Hey, - this is who I am. - These air secret like I have these right, - and, - ah, - Windows, - who I am clicking on numbers here at the top will show us the numbers that we've bought, - so you can buy multiple numbers if you want. - As you've seen, - they gave us a default number, - but if you want to put as many numbers, - you know we could buy a new number. - They are a dollar each. - That's a dollar for most normal numbers in $2 for a 1 800 number. - And then if we click into the number, - so want to click into the number here, - you'll see we have some options. - So here, - voice requests your l. - What this is saying is that if I put a direct link to a file right, - like a file on my server, - when I call this number, - Twilio will read the code in this file and do whatever I tell it to Dio. - That's pretty cool. - That's what you want to do. - It would be cool if we could call this number right and then write a message in some code. - It's like, - Hey, - how's it going right? - Or it could place a music for us or a bunch of different things, - and so that's what we're gonna do now we're going to write some code in sublime right and - sublime text editor, - and we're gonna uploaded to the server and then we're gonna find that link and put it here - so that when we call this number, - any of the code we write is going to executed. - So I want to direct you to the class files, - and here I have a template that I've made. - And if I just open this up in supply, - I'm you'll see that it's just two lines of code. - This is gonna be the header that we're gonna need just the top of our pages. - So I just did that for you just cause it makes it easy less copying and pasting. - Um and we have it here. - And so what I'm gonna do is I'm gonna create a duplicate of this and rename it, - and I'll call this Say hello. - So now I have in my template, - just in case you guys need to come back and you want to make a new one later and we're just - gonna work in the copy. - Say hello. - I'm gonna open this in sublime when you make a call and interact with Giulio. - We use the language of twin will. - This is a market language that twilio has created for us. - Interact with, - and it's pretty easy to get started with. - Here is an example a response. - And if I call, - you're gonna get a voice of a woman that's going to say, - please leave a message after the tone, - hopefully with not his deep voice and ah, - in a way to record. - All right, - But this is the twin language, - and you may notice from a previous lesson that this is really just some XML code. - It's some XML co that they've standardized for their system so that when you use thes calls - , - you get a certain kind of response. - We're gonna look a twinkle in a little more in just one second. - But I also want to point out here, - um, - the helper libraries here So twilio can be accessed using any programming language here, - and you can see they have libraries for each of the language that will help you out. - So these are just based to get you started. - And there's so many good ones. - Maybe once you've never even heard of the great thing about using the twilio a p I is The - documentation is so well written. - I think they make it just so easy to get started and to even learn about the concepts of AP - eyes. - If you are new, - JP II's in general and so that's why I would recommend it. - Facebook is also good. - I find Twitter to be confusing lately for for newbies and, - um not recommending that. - But this is working really well, - so you can see we can use it for all the different languages. - And they have a bunch of how twos. - So then, - for each of the languages, - these are tutorials that they've written step by step. - You can see this one. - They have the code for PHP. - In Ruby, - you can go down call screening so that you can set up all these. - Really? - They're just applications, - right? - These are applications that someone has written that twilio is written for us. - Teoh, - do some really cool stuff and the list goes on and on and on. - This is a great way. - You can go in here and just copy some code. - Read the documentation. - What did they dio right, - But before we go there. - You may need to understand. - Well, - how do we start writing the code and where do we put it? - So that's what we're gonna look at here so that you can just write some of the most basic - twilio commands and get it going. - So that is so. - That is why we're going to use twiddle. - Okay, - So twin will Here, - we can look through it. - You can see we have some twin will verbs so we can do things like, - Say, - which is gonna say a message to us will read the text, - right? - Play is gonna play some audio, - etcetera, - etcetera. - Let's just try what say first, - How would we invoke say verb? - We're going to come to our code here. - And remember I said, - this is the header. - This needs to be there, - and we're going to start off by righting response. - Great. - And so everything between their if we put a twilio, - the twin will actually a verb. - We'll get executed so I can write something like that and that's all we need. - And so now I can save this and I want to put it on my server. - Once it's up on my server I just need to go find the URL Cool. - There's the file I created. - And there we go. - That's what you want to see. - So there's some XML, - and that's exactly how it should look. - And this is the direct link to that code. - So now let me to do is take this code and paste it in here underneath her number. - So a voice, - a crest, - and this is where it will go. - So that looks good. - I can save this change. - Great. - Awesome. - So let's give it a try. - I'm gonna call this number now. - Hello. - Thanks for being awesome. - And it worked. - Yeah, - that's all there is to it. - So, - in addition, - you can click on numbers here, - twilio numbers, - and I have that open and you can buy another number if you want. - Here's where you would come to buy toll free number. - Of course you're going to pay. - Like I mentioned, - it's gonna be $2 for that. - So there's some other features here we can look at. - We can also look at the logs and the logs will take a snapshot of whoever is calling that - number. - So I just call that number and there it is. - This is the call I made and have a record of that number. - There 11. APIs for Every Occasion [5:35]: - so there are thousands of AP eyes available on the Internet that you can start reading the - documentation for and getting set up with. - You have the basics of Jason XML. - You know how to set it up under server by now, - and we have a little bit of an idea of how access tokens will be needed to give us off - indication. - Usually, - you'll need some kind of access token for most AP eyes. - Here's a view use cases that I've seen for interesting ways of influencing AP eyes. - So again, - just at a higher level here was gonna kind of overview and look at some implementations. - Puppy stream. - This is a startup. - They were wondering, - How could we launch a photo sharing site without building a mobile app? - Right, - So they didn't have the resource is to build a mobile app, - but they wanted to have a way that somebody could upload via their phone. - Well, - you know, - why reinvent the wheel if you think about it? - There's already so many photo applications on your phone are ready. - And so what puppy stream did was they used instagram and via the AP? - I now think about how this works on their site that middle bit there, - that yellow middle bit. - They have what's like a listener. - It's a listener, - and it's just basically looking at when people upload on instagram, - right? - And if someone uploads on Instagram, - who's also authenticated with site So a user off, - um, - uploads via instagram and hashes it, - puppy stream. - Well, - then the puppy stream site. - It recognizes it goes up somebody who's a user of the site and just did a hash puppy stream - is here. - Let's grab that photo So it takes in that Jason, - you know, - similar to how you would take photos with Facebook, - right in our example. - And it takes that Jason and it pulls in in, - and it stores that photo on the puppy stream site. - It makes reference in their own database rights. - Now they have captured that data, - and that's a pretty easy way to do it, - to leverage what's already out there. - And you can even then Macon automation to then post it to Facebook on behalf of this user, - right? - So all they have is this one code base in the middle, - but they're leveraging different AP eyes to make its social and to really not reinvent the - wheel with technology, - Sonar was wondering, - You know, - how can we bring in connections from other social media sources? - The problem they had was, - you know, - just the empty party problem. - You download an app in the APP store, - you come on, - nobody's using app. - So how do we solve that problem there wondering? - Well, - they decided they could take existing data from foursquare Twitter, - Facebook and populate their app. - So it looked like other people were using the app. - If you're not familiar with how the APP works, - it's looking for friends and friends of friends in the area. - So if I log on now, - it's saying, - You know who else at this party who's a friend or who's a friend of a friend that maybe I - don't know who around the block it yet. - It's maybe a little little 100 0 brooking on your privacy a little bit, - but that's how it works. - And, - um, - yeah, - and so they use this data so that when you come on, - even if none of my friends are using it, - it's saying, - Hey, - you know, - someone just checked in around the corner on Facebook, - you know, - someone just used foursquare. - Here's their likes, - and you can see all of this data. - See, - Net is a company in a website that does reviews of electron ICS, - telephones. - TV is all that. - Over the years they've acquired different partner sites, - right? - And when you have a bunch of different sites coming together over the years right, - they could be written in. - That's a different languages or have different practices where their own best practices - their own developers working on these segments. - How do we unify that data? - How would we bring that all together so that we can share it internally, - Right amongst all the partner sites? - One of the developers from Cnet was speaking at mastery, - and he explained how this problem worked. - I'm not actually sure that these were the languages, - but using this as an example. - So they had all of these different acquisitions, - and they wanted to bring them together, - right, - And each of them has their own data flow in their own databases. - But we needed a way to unify this data. - So what he came up with was an internal A P I, - and the internal AP. - I said, - you know, - it doesn't really matter that we have all these different databases and always different - this stuff all around the Net. - We can make an A p I. - And maybe they used XML. - Maybe they used Jason, - but the idea being they used one uniform call and wait to interface with the data in a way - that we could make this whole system flow much more fluidly. - So in closing, - there are a lot of AP eyes out there. - Here's just a few Foursquare has geo data, - you know, - if you need a email newsletter. - AP I mail. - Chimp has ways you can integrate their product, - discuss payments. - Google has tons of a P eyes. - You probably don't even know they have the prediction. - A p I is amazing and we're check that one out. - Ah, - and AP eyes even for real life things around us. - So thanks a lot. - Here's the block will post up additional questions from my class and resource is and you - can reach me on Twitter at Stig. - Thanks for watching
