X API can share Community posts with followers via share_with_followers

What this means for you

Communities on X are groups built around a topic. When you post in one, only the group usually sees it. On x.com you can tick a box to show it to your followers too. Apps that post for you can now do the same, so a scheduled Community post can reach both the group and your followers.

The details

• New parameter (July 28, 2025): share_with_followers (boolean, optional) on POST /2/tweets. With community_id set and share_with_followers: true, the Community post is also broadcast to the authenticated user's followers' timelines.
• Related field (November 22, 2024): X added the community_id Post field to API v2. The Create or Edit Post reference describes community_id in the request body as the "Community to post the tweet to" (numeric ID, up to 19 digits).
• Doc mismatch: the Create or Edit Post schema currently describes share_with_followers as "Share an exclusive (super-follower) tweet with all followers", which differs from the changelog. Test both cases before relying on either reading.

What to do next

• Business owners: Nothing.
• Marketers and agencies: If you post to X Communities, ask your scheduler whether it supports sharing those posts with followers.
• Developers: Add a share-with-followers option next to community_id in your post composer and send share_with_followers: true when it is ticked.
