We have a need to do the following a) allow the user to post using our canvas app. The post is a simple TextPost, though it could be a CanvasPost b) After the user clicks share, get the feedItem record Id of the just posted item and do some stuff with that record.
To put it mildly I'm a n00b here, and it confuses me that there appears to be no easy way to do this?
Clarification: The canvas app is called from a publisher action
