Creating Chatter Records
Creating a Chatter record requires using the GenericEntity class.
GenericSalesforceEntity feedItem = new GenericSalesforceEntity("FeedItem"); //The ParentId is the ID of the sObject that the Feed Item is attached to. In this case it is a Contact ID. contactFeed.InternalFields.SetField("ParentId", "0039000000Msoqj"); contactFeed.InternalFields.SetField("Body", "Some chatter text"); GenericSalesforceService chatterContactService = new GenericSalesforceService(GetSalesforceSession, "FeedItem"); SaveResult saveResult = chatterContactService.Insert(feedItem);
