Intro to developing for @twitterapi

And the just wacky...

What is ?
How to use the Twitter Platform

What is ?
‣ REST API
‣ provides the “basic” functionality - tweet, follow, etc.
‣ all functions available on your timeline on twitter.com
‣ Search API
‣ real-time search index
‣ get “top tweets” / relevant search results
‣ Streaming API
‣ HTTP long-poll connection
‣ tweets come out of the system in real-time

The goals of
‣ To be ridiculously simple
‣ To be obvious
‣ To be self-describing

Tools of the trade
‣ dev.twitter.com
‣ documentation center
‣ API console for quick testing and exploration
‣ curl and a web browser
‣ testing unauthenticated endpoints
‣ CLI to get a raw dump of the interaction
‣ twurl
‣ OAuth-enabled version of curl

Authenticating to
‣ OAuth 1.0a
‣ signing “write” requests
‣ give visibility into the stack
‣ Applications don’t have a user’s username / password
‣ user can change password at any time
‣ user is secure in knowing his/her password not being stored outside
of
‣ user can revoke permissions to app at any time

Libraries
‣ PHP - http://github.com/abraham/twitteroauth
‣ Java - http://github.com/fernandezpablo85/scribe
‣ Ruby - http://oauth.rubyforge.org/
‣ C / C++ - http://liboauth.sourceforge.net/
‣ Actionscript / Flash - http://code.google.com/p/oauth-as3/

twurl
‣ http://github.com/marcel/twurl
‣ Command line tool to interact with using OAuth
‣ Transparently handles OAuth signing against
‣ authorize against to get access tokens
‣ from there on out, all requests are signed

Limits
‣ 350 API calls/hour using OAuth against api.twitter.com
‣ unauthenticated it goes against the source IP address
‣ authenticated it goes against the calling user
‣ “Natural” limits on
‣ number of tweets sent
‣ number of DMs sent
‣ number of followings / unfollowings
‣ Status limits
‣ can’t have duplicate tweets
‣ can’t have malware links in tweets

Anatomy of the
REST API
What if I want to write code?

GETing from the API
Reading, reading, reading

GETing from the API
‣ For most cases, completely wide open
‣ Can do a HTTP connect and a simple GET request
‣ “Protected” information may require authentication (covered later)
‣ getting the tweet of a protected user
‣ getting the timeline of a user

Status objects
The basis of everything

Getting a status object
‣ Figure out the ID of the status objects
‣ Construct the URL for statuses/show
‣ Grab it!

Taking a look at status 13762161921
‣ Build the API URL
‣ http://api.twitter.com/1/statuses/show/
13762161921.xml
‣ http://api.twitter.com/1/statuses/show/
13762161921.json
‣ If it’s a public status, then just fetch it
‣ use a browser!
‣ use curl!

The fields you really need
‣ id - the unique identifier for the status
‣ text - the content of the status update
‣ created_at - the date the status was created at
‣ user/id - the unique identifier for the status creator
‣ user/screen_name - the name of the status creator
‣ user/profile_image_url - the URL to the creator’s avatar

Getting an user object
‣ You can do this with a screen name or an ID
‣ Construct the URL for users/show
‣ Grab it!
‣ (and, status objects do have embedded users)

Taking a look at @raffi
‣ Build the API URL

‣ Just fetch it!

‣ screen_name - the screen name of the user
‣ name - the name the user entered on his/her settings page
‣ profile_image_url - the URL to the creator’s avatar
‣ description - the description the user entered on his/her
settings page
‣ url - the URL the user entered on his/her settings page

Timelines
Getting lots of tweets

Timelines
‣ “Arrays” or “lists” of Tweets
‣ in XML, wrapped with <statuses>...</statuses>
‣ in JSON, regular array [...]
‣ Sorted (mostly) chronologically (hence “timeline”)
‣ When statuses are created in the system, they are fanned-out to
timelines

Few different timelines for the user
‣ user_timeline - all the tweets you created
‣ friends_timeline - all the tweets that people you follow have
created (sans native RTs)
‣ home_timeline - next generation friends_timeline in that it
contains native RTs
‣ mentions - all tweets that @mention you

‣ Some don’t require authentication and some do

Taking a look at @raffi’s user_timeline

Search API
Sifting through large amounts of Tweets

Search API
‣ History
‣ Summize was purchased in 2008
‣ built their own real-time search engine
‣ Still a separate system from main Twitter stack
‣ separate database and indices (only goes back 10-14 days)
‣ different representations of data
‣ different overall status object
‣ different user IDs
‣ different output formats (Atom, instead of XML, and JSON)
‣ Search is a corpus of best quality Tweets

Running a simple query
‣ Just GET with a q parameter - that’s it!

Advanced operators
‣ from - restrict results to tweets from a particular screen name
‣ result_type=popular - find both “best” tweets and temporally
relevant tweets
‣ Textual operators
‣ OR to combine queries - http://search.twitter.com/
search.atom?q=leeds+OR+london
‣ - to negate - http://search.twitter.com/
search.atom?q=leeds+-from%3Aimran

What @raffi usually does
‣ Use the web interface on search.twitter.com to construct the
query
‣ Tweak it and shorten it
‣ Switch the result format to be in API compatible format
‣ Use that!

Trim down the URL
‣ http://search.twitter.com/search?q=&ands=leeds
+twitter&phrase=&ors=&nots=&tag=&lang=all&from=imran&t
o=&ref=&near=&within=15&units=mi&since=&until=&rpp=15
‣ Strip down to only where our custom data is
‣ ands - where the query is
‣ from - restrict it to @imran
‣ make the format atom to get an API friendly response
‣ http://search.twitter.com/search.atom?ands=leeds
+twitter&from=imran

Trends API
What’s going on right now?

Trends API
‣ Trending topics are used for content discovery - powers the front
page and logged out experience of twitter.com
‣ API provides both global trends and local trends
‣ Timescale
‣ global trends are provided for “now”, and summaries of the
past day and week
‣ local trends are only provided for “now”

WOEIDs
‣ “Where on Earth Identifiers”
‣ http://developer.yahoo.com/geo/
‣ Provides “stable” and “language neutral” identifiers for places in
the world
‣ Twitter has the World (WOEID of 1), and a series of countries and
cities in its trends database

Streaming API
I need it now, now, now, now, now

Streaming API
‣ Maintain a persistent connection to servers
‣ Get pushed a tweet that matches your predicate in “real-time”
‣ Most useful for server to server integrations
‣ Beginning to experiment with server to client integrations

Get a sample of all the tweets
‣ Use curl for a really simple proof-of-concept client
‣ http://stream.twitter.com/1/statuses/
sample.xml
‣ Requires basic authorization (username and password)
http://stream.twitter.com/1/statuses/sample.xml
‣ Only one connection per username

Get the tweets from certain users
filter.xml
‣ Can pass in a list of user IDs
‣ up to 400 users (passed as follow with CSV IDs)
‣ get their tweets as they are getting created

Get the tweets containing a certain word
filter.xml
‣ Can pass in a list of words
‣ up to 200 users (passed as track with CSV IDs)
‣ e.g. Twitter will match TWITTER, twitter, “Twitter”, twitter.,
#twitter, and @twitter
‣ get tweets as they are getting created
