# Edit published post

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

Edit the text of an already-published post. Supported on X (Twitter), Discord,
Facebook, Reddit, LinkedIn, Telegram, Pinterest, Google Business Profile, YouTube,
and Slack. When a post was published to several accounts on the same platform,
pass `accountId` to pick which account's copy to edit (the first entry is edited
otherwise). 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

**LinkedIn**
- Text only, no time limit. Media, polls, articles, and reshare targets cannot be
  changed
- Works for member and organization posts published through this API. The post
  keeps its ID and LinkedIn shows an "edited" marker
- Text is limited to 3,000 characters; mentions and hashtags are preserved

**Telegram**
- No time limit; messages published through Zernio are editable indefinitely
- Text posts: edits the message text (up to 4096 characters)
- Media posts: edits the caption only (up to 1024 characters). The media itself
  cannot be swapped
- For albums, the caption shown on the album (its first message) is edited
- The message ID is unchanged

**Pinterest**
- Description only, maximum 800 characters. Media, link, and board cannot be
  changed, and a pin title derived from the old content's first line at publish
  stays as-is
- Pinterest's pin-update endpoint is currently in closed beta; until the app is
  allowlisted by Pinterest, edits are rejected with a "beta feature not yet
  enabled" error
- The pin ID is unchanged

**Google Business Profile**
- Post body (summary) text only. Call-to-action, event/offer fields, and media are
  untouched
- No time limit and no edit limit. The post ID is unchanged
- The post must still exist on Google: a post deleted from the Business Profile
  dashboard, or an event/offer post past its end date, returns a 404

**YouTube**
- `content` replaces the video description only. The title is unchanged, even if
  it was originally derived from the content's first line at publish time
- Title, tags, thumbnail, and privacy edits belong to `POST /v1/posts/{postId}/update-metadata`
- No time window and no edit cap. The video ID is unchanged

**Slack**
- Text only, up to 4,000 characters. Media cannot be swapped, and media posts
  whose share message reference never resolved cannot be edited
- No time limit unless workspace admins restrict message editing
- The message 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.
