Should an issue seemingly unique to Facebook be encountered, or so much as confirmed in discussion with a BoxCast representative, you may report the issue as outlined here.
As of January 2020, Facebook doesn't support streaming to EVENTS through its API. If you're trying to stream to an event, you'll want to set up another RTMP destination.
BoxCast gives you the ability to stream to your Facebook page, timeline, group, or event. In this article, we'll outline how to stream to your group or event. If you want to stream to your Facebook page or timeline, click here to learn more. Follow these steps to stream to your Facebook Group or Event.
Log in to the BoxCast Dashboard and go to Settings, followed by Integrations, and link your Facebook account. If your Facebook account is already linked, please click the Re-Link Integration button if this is your first time streaming to a group or an event.
Go to facebook.com and click on the group you wish to stream to. You must be an Administrator of the group to set up live streaming. Once you get to the group scroll down the left side menu to Settings:
Scroll to the bottom of the Settings to Advanced Settings and click Apps.
Click on "Add Apps."
Search for BoxCast and click the BoxCast app that comes up.
Schedule a broadcast in the Boxcast Dashboard and select the group you wish to stream to.
Step 8 (Optional):
Once the broadcast is scheduled, click on Create the scheduled live event now to show your group members you'll be going live at a certain time.
Once you go live, the broadcast will automatically appear on your group page.
If a group hasn't added the BoxCast app and a user tries to post there, all account users will get an email like this one. Please add the BoxCast app to the group before streaming.
