Follow up from #345.

Have you tried authing with Facebook with the new app scope?

I now have setup my own build and docker deployment process so I can test on my server.
After the painful configuration at https://developers.facebook.com (and successifuly receiving an auth token) I'm one step further.

ERRO[0993] [Facebook 2]: Error: [message:(#200) If posting to a group, requires app being installed in the group, and \
          either publish_to_groups permission with user token, or both pages_read_engagement \
          and pages_manage_posts permission with page token; If posting to a page, \
          requires both pages_read_engagement and pages_manage_posts as an admin with \
          sufficient administrative permission] [type:OAuthException] [code:200] [subcode:0] 

So yes, the scopes are working.

@muesli, is the Facebook Hive capable of posting to a Facebook page? Because that's what I'm trying to achieve. 😀

It seems like pages are a different thing, you need a page access token, https://developers.facebook.com/docs/pages/publishing.

I must admit I've kinda stopped using Facebook personally, but have so far only used it to post on my personal page - which Facebook now doesn't permit anymore.

Posting to pages via the API should still be doable, though. We may or may not have to adapt to their newer API versions.

Facebook posting was always kind of flaky (back a few years ago when I wrote my own publishing integration) since access tokens seem to expire from time to time...

Thank you, @pbek!
