Follow us @forcedotcom

29. Chatter API or SObject REST API?
 Chatter API:
– Semantically rich resources
– Localized presentation-ready data in JSON or XML form
– Comprehensive feed data in a single request
– Matches the web UI
 SObject REST API:
– Data directly from the database
– Arbitrary SOQL queries
 The same Oauth tokens can be used for both
Follow us @forcedotcom

30. Tips - General
 Group feeds are just record feeds
– /chatter/feeds/record/<group id>
 Security model of UI is observed
– News feed can only be retrieved for the logged-in user
 Following an object is described by a “subscription”.
DELETE the subscription to stop following
 Use 'Accept-Encoding: gzip, deflate’ HTTP header
 Always encrypt your Oauth access and refresh tokens
Follow us @forcedotcom

31. Rate Limiting
 Rate limiting:
– each user + remote access app combination gets 200 requests
per hour
 Requests to endpoints outside /chatter and /connect are
not counted in this rate limit
– Image requests not rate limited
– Sobject API requests count against org-wide rate limit
 Use separate remote access apps for production and
development to avoid being rate limited
– Also use different users if your automated tests run often
Follow us @forcedotcom

32. Tips – Javascript served from non-salesforce domain
 Use a controller pass-thru to work around Single Origin
Policy for ajax requests
 Two approaches to rendering:
– pass JSON responses through server as-is and render using
client side template library such as Mustache, Handlebars, or
Eco
– Deserialize and render to HTML on the server and send to client
 Requests from HTML (img tags, HTML forms) must also
use controller pass-thru to put Oauth token into HTTP
header
Follow us @forcedotcom

33. Tips – Javascript served from salesforce domain
 Can make ajax requests directly to Chatter API and
render to HTML on client.
– When Connect in Apex goes GA, you can also make requests to
a controller to get custom rendered HTML.
 Use an ajax proxy if you’re on a custom domain. (see
the salesforce ajax toolkit) to work around SOP.

34. Tips – Apex
 Apex Now
– Call the Chatter API using Apex callouts
– Use session Id from UserInfo
 Apex Future
– ConnectAPI class will provide Chatter API resources directly
Follow us @forcedotcom

35. Connect in Apex (Pilot in Summer)

Apex
 Use cases include:
– Customized social experiences in Visualforce
– Custom Chatter feed rendering in Visualforce
