# Update conversation

`PATCH https://api.endless.app/conversations/{conversation_id}`

Source: https://endless.app/docs/api/conversations/update

Updates a conversation and returns the updated row. Scoped to the conversation named by `conversation_id`. Send a sparse body — only the fields that changed. Each field is authorized on its own, so resending an unchanged one also demands its permission.

## Authentication

- `bearerAuth`: HTTP bearer (JWT)

## Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `conversation_id` | path | string (uuid) | yes |  |
| `Endless-Api-Version` | header | string | no | Pin the caller to an API major (`1`). Omit to accept the current version. A major this deployment cannot serve is refused with 400 `unsupported_api_version`. |

## Request body

Content type: `application/json` — object

- `title` (string | null)
- `active_leaf_id` (string | null)
- `only_if_untitled` (boolean)

### Errors

- `400` (Error): The request is malformed, or failed input validation. `message` names the field and the rule it broke; `data.issues` carries them individually.
- `401` (Error): No bearer token, or a token that failed verification.
- `402` (Error): The workspace has no credits left, or the caller is over a spending limit.
- `403` (Error): Authenticated, but the caller's role in this workspace does not carry the permission this operation needs.
- `404` (Error): No resource with that id, or the caller cannot read it. The two are deliberately one answer, so an id cannot be probed for existence.
- `409` (Error): The request is well-formed, but the resource's current state forbids it — a taken name, a last admin, a limit already reached.
- `429` (Error): The caller has spent its rate-limit window. `Retry-After` says when to come back.
- `500` (Error): The request failed on our side. Safe to retry an idempotent operation with backoff.
