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.
Follow us @forcedotcom
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)
Exposing the same Chatter API resources and data in
Apex
Use cases include:
– Customized social experiences in Visualforce
– Custom Chatter feed rendering in Visualforce

– Modifying user and group photos in Apex
Taking pilot nominations over the next two weeks.
