# Edit published post

`POST /v1/posts/{postId}/edit`

Edit the text of an already-published post. Supported on X (Twitter), Discord,
Facebook, and Reddit. Each platform enforces its own rules:

**X (Twitter)**
- Connected X account must have an active X Premium subscription
- Must be within 1 hour of original publish time
- Maximum 5 edits per tweet (enforced by X)
- Threads cannot be edited, only single tweets
- X assigns a NEW post ID on edit, returned as `id`

**Discord**
- No time limit and no premium requirement
- The message ID is unchanged after the edit

**Facebook**
- Graph only permits editing a post that the same app created, so this works on
  posts published through Zernio and is rejected for posts created in Meta
  Business Suite / Composer or by another tool
- Media cannot be swapped, only the message text
- Reactions, comments, and shares are preserved. The post ID is unchanged

**Reddit**
- Self-posts only. A link post has no editable body and is rejected before the write
- Body only. Reddit exposes no API to edit a post title, ever
- The post ID is unchanged

Media edits are not supported on any platform. The post record in Zernio is updated
with the new content and an edit-history entry.
