What is ? The Twitter Platform
Saturday, July 24, 2010
TM
What is ? ‣ REST API
‣ provides the “basic” Twitter 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
Saturday, July 24, 2010
TM
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

OAuthpocalypseThe day is 30th June 16th August 2010
Saturday, July 24, 2010

What you need to know‣ All applications must be using OAuth for the REST API
‣ Streaming API will still support Basic Auth
‣ Search API has no auth
‣ Replace curl with twurl for debugging
http://dev.twitter.com/pages/auth_overview
http://github.com/marcel/twurl
Saturday, July 24, 2010
TM
OAuth Methods‣ Web must use three legged OAuth
‣ Desktop and mobile apps can also use out-of-band OAuth
‣ Some desktop and mobile apps will be considered for xAuth
Saturday, July 24, 2010
TM
xAuth not XAuth
xAuth is OAuth
