# Rename, archive, or pin a named chat session

`PATCH /assistant/chat/sessions/{id}`

## Request

- Base URL: `https://api.mobilerun.ai`
- URL: `https://api.mobilerun.ai/assistant/chat/sessions/{id}`
- Auth: HTTP bearer

Rename, change status, and/or pin. Title updates apply best-effort. Archiving always clears the pinned flag. `title` is rejected with 409 `code: "session_title_managed_by_workflow"` when this chat is bound to a workflow — a bound chat's title is managed by the workflow. Other fields (description, status, pinned) remain updateable; archiving a bound chat stays allowed.

## Path parameters

- `id` string, uuid, required

## Request body

- object
  - `title` string
  - `description` string, nullable
  - `status` 'active' | 'archived'
