## Unsubscribe from events

`POST /v1/chats/events/unsubscribe`

Stops accumulating messenger events for the current user. After unsubscribing, new events are no longer accumulated. If there was no subscription, the call does not return an error.

## Parameters

The endpoint takes no parameters. The request body is an empty object `{}`.

### curl — personal key

```bash
curl -X POST "https://vibecode.bitrix24.com/v1/chats/events/unsubscribe" \

```json
{
  "success": false,
  "error": {
    "code": "SCOPE_DENIED",
    "message": "This endpoint requires 'im' scope"
  }
}
```

## Errors

| HTTP | Code | Description |
|------|-----|---------|
| 403 | `SCOPE_DENIED` | The API key does not have the `im` scope |
| 401 | `TOKEN_MISSING` | The API key has no configured tokens |
| 422 | `BITRIX_ERROR` | Bitrix24 returned an error (error text in `message`) |
| 502 | `BITRIX_UNAVAILABLE` | Bitrix24 is unavailable or returned a server error |

## Known specifics

**OAuth key.** For a `vibe_app_…` key add the `Authorization: Bearer <session_token>` header — without it the request returns `401 TOKEN_MISSING`. Learn more — [Keys and authorization](/docs/keys-auth).
