This document provides an overview of Facebook APIs and applications. It discusses widgets like the Like button and Facepile that can be copy-pasted and used to create Facebook Pages. Pages are described as hubs for brands or organizations to have a presence on Facebook without being a profile. Facebook Connect is covered as a way to add social features like login and friend access to external applications. The document also outlines the application registration process and tools developers have access to like the Graph API and FQL for building applications that integrate with Facebook user profiles and social graph.

1. FacebookGonna say some techie stuff about APIs and that

2. Anatomy
1. Widgets
2. Pages
3. FB Connect
4. Applications
x. The Facebook vision

3. 1. Widgets
● Very easy, very powerful, copy and paste
● The “like” button, Facepile, comments box, etc
● “Like” button + Open Graph = a Facebook Page!
● Advantages: viralness, Facebook brand
● Analytics facebook.com/insights
● 'Like' or 'recommend'

4. 2. Pages
● For when you want to be on Facebook but not as a friendable
person
● Ready made hub, could even replace a website. Easy viralness and
kudos of FB brand.
● Default tabs: wall, info, photos, etc
● Can change 'home' tab
● Custom tabs: Big deal.
● FBML being deprecated for iFrames.
● Loads of applications can run in tabs
● Most notable are apps that integrate with the wall, eg; cross-posting
Twitter feeds, blog posts, Flickr photos etc
● NB. That Joe Public can make these Page-integrating apps
● You can get the 5000 most recent fan IDs of a social object

5. 3. Facebook Connect
● Bonafide application territory; but, basic user-management is
enough of a feature in itself
● 'Basic information' = Full name, profile pic, gender, friends,
'everyone' data
● Permissions. Don't ask for too many.
● publish_stream, offline_access, email, read_stream (Activity Streams
standard), read_inbox, xmpp_login (XMPP is another open standard)
● photos, videos, etc and you can ask to access these for the app user's
friends!
● Can ask for permissions when user first connects to app or can 'extend'
at any point afterward too.

6. ● Internal Vs. External
● Extra JS SDK methods for iFrames; dynamic resizing of iFrame
and messing with the URL
● Mafia Wars, Farmville. Don't know anything about them because
I blocked them from my stream :(
● Graph API
● Replaces old API. The new 'open' vision, more structured,
everything is a social object.
● True RESTful API interface
– Means lots of SDKs; PHP, Ruby, Python
– https://graph.facebook.com/me/friends?access_token=[foo]
– http://graph.facebook.com/tbuckleyhouston/picture
– JSON
4. Applications

7. ● developers.facebook.com/setup
● Receive App ID and secret
● Lots of settings
● Icon, logo & FB Connect logo. Named developers. Email contact.
● All apps get their own bonafide FB Page
● Important links;
● developers.facebook.com/blog/feed
● developers.facebook.com/live_status
● facebook.com/insights
● Bug tracker
● Forums
● Documentation
STEP 1. Registering

8. Surprisingly easy :)
<div id="fb-root"></div>
<!--<script src="http://connect.facebook.net/en_US/all.js"></script>-->
<script src="http://static.ak.fbcdn.net/connect/en_US/core.debug.js"></script>
<script>
FB.init({
appId : 'YOUR APP ID', // [REQUIRED]
status : true, // check login status [OPTIONAL]
cookie : true, // allows server to access the session [OPTIONAL]
xfbml : true // parse XFBML [OPTIONAL]
});
</script>
STEP 2. Hello World

9. ● Either XFBML or JS's FB.login()
● OAuth 2.0 (NB. Facebook is an OpenID relying party)
● Cookie is registered which can be used by server-side
SDKs.
● XFBML: X stands for XHTML, JS SDK parses it.
● Canvas legacy. Relatively useless. FBML only used by Page
Tabs now and not for much longer either.
– Simple <fb:name>
– Complex <fb:multi-friend-selector>, <fb:comments>
cannot be provided in any other way.
STEP 3. Add a login button

10. ● JS SDK has 1 other class of methods unique to it; FB.ui
● Dialogs, exteneded permissions, posting to user's wall, sharing, etc.
● The API:
● JS has it (FB.api) just like all the others (PHP, Ruby, etc).
● You can read and write to and from user's (and Pages) accounts.
● Subscribe to individual real-time updates!
● Progromatically access analytics.
● You are rate limited, but it's a secret :s
● You are now allowed to cache data indefinitely (may be 1 or 2 exceptions)
● FQL:
● Very powerful, worthy of a page in itself. Sub queries, multiple queries per
API call.
● Read-only.
● AFAIK everything can be accessed through FQL!
STEP 4. Do stuff
