# Update post content

`PUT /api/apps/{app_id}/virality/posts/{post_id}`

<Info>This API is in beta. Endpoints, fields, and behavior may still change, so avoid depending on it in production.</Info>

Replaces a post's text with the text you supply, and returns the whole updated plan.

This is the plain-edit counterpart to [Refine a post](/api-reference/refine-a-post). It saves the text you send, calls no language model, and costs no credits. Only the post's `content` changes, so its image and every other post stay as they are.

<Note>The text is sanitized before it is stored, so what you read back can differ from what you sent. XML and HTML tags, code fences, and lines starting `system:`, `assistant:`, or `user:` are removed. Read `content` off the response rather than assuming your input was stored verbatim.</Note>

A 409 means repeated write conflicts on the plan did not settle, so retry the request. This endpoint shares a limit of 15 requests per minute with the other social content endpoints.

<Note>This endpoint accepts a personal API key. Workspace API keys are not authorized for it and are rejected with a 403.</Note>

<Warning>The response includes fields beyond the ones documented here. Don't rely on undocumented response fields, as they can change at any time. Send only the fields documented here. Other request fields are not supported and their behavior can change.</Warning>

## Path parameters

- `post_id` string, required — ID of the post, as returned in the content plan. Must be a UUID.
- `app_id` string, required — ID of the app.

## Request body

- UpdatePostPayload
  - `content` string, required — The post text to save, replacing whatever the post held before. Sanitized before it is stored, so XML or HTML tags, code fences, and lines starting `system:`, `assistant:`, or `user:` are removed.
