Chatter API Tips

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

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

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

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

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.

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

Connect in Apex

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 –  Posting feed items with @-mentions in Apex

–  Modifying user and group photos in Apex

Connect in Apex Demo

Take Aways

§  Chatter can drive better user engagement with external applications

§  Easy to build integrations with existing applications

§  Wealth of interesting use cases emerge from news feed integration.
