Sorry for the delayed response. The process for creating an action for a new review would be similar to our
JomSocial Photo Upload Action
example.
The only differences are that you'd want to change the names of your actions and objects to be 'review' and 'business' or something like that to be more correct for reviewing things.
Then, in JFBConnect, you'd want to:
* Create a JReviews Object instead of a JomSocial Photo
* Create a JReviews "Review" action instead of a JomSocial Photo Upload action
That will automatically trigger when a new review is placed and should do what you're looking for. If you have any questions, please let me know. Open Graph Actions can be tedious to setup in Facebook (and JFBConnect), but our documentation should walk you through it.
Thanks,
Alex
