Publishing on Facebook Groups has a couple of specifics that you should know about:
You have to be an Admin of the Group on Facebook because you'll need to link Agorapulse with your Group - only Admins can do that, Group members are not allowed to do so.
You will be posting as yourself rather than as a group or a page.
As Facebook says, "...post content on a Group on behalf of a group member who has granted your app [note: Agorapulse] permission to do so."
This is different to publishing on Facebook Pages, where you actually publish as a Page. The post might look like this, for example:
You can't mention other Groups, Facebook profiles or Facebook Pages in posts. This option is not supported by Facebook API.
