I'm looking to have my app post to a non-owned Page AS one of the user's owned pages (owned-page Posted to non-owned-page's feed).
If you log in to Facebook as your page, you are allowed to do this on the desktop platform. However, my trials (and search) have returned that it's "not possible" to execute via Facebook Graph API.
Specifically when I execute the following POST:
/{target-page-id}/feed?message=test&access_token={owned-page-access-token}
I receive the following response from FB:
(#200) Posts where the actor is a page cannot also include a target_id\n other than EVENT or GROUP
Posting to Event or Group works, but doesn't allow me to post to a target page.
Any workarounds? Having a hard time grasping that you can do it on the desktop portal but not via the API
Thanks in advance!
