Scheduling Good to Knows

Sharing links 

Facebook Stories 
  • We are unable to add captions or text overlays to stories at this time. 

Facebook Reels

  • Due to API limitations, it is not possible to add trending music to reels. Therefore, we recommend adding music to your video file before uploading it to Buffer.
  • The Facebook Reels API does not support locations, so you will not be able to add a location to your reel.
  • When your reel is published, it will also appear on the feed.

Facebook Group posts

  • We use notification publishing for Facebook Group posts. This means you can create a post in Buffer and then, when it's time to post, you'll receive a notification on your mobile device that you can tap to open and copy your post over to your Facebook Group to finish posting. Learn more about how this works here

Multi-language posts

  • It's not possible to create a Facebook post in multiple languages through Buffer at this time. You would need to create such posts within Facebook itself and you will need to be an admin on the Page.
