I am looking to extract user post data within a Facebook group, which include but is not limited to: Post-ID Post-Author Link to post Time created Message City Country Latitude and Longitude Likes Comments Attachments Images I am a registered developer on Facebook and an admin of the relevant Facebook groups. The app has already passed an app review for groups_access_member_info and Groups API.
