```
HTTP/1.1 204 No Content
```

422 — activity not found:

```json
{
  "success": false,
  "error": {
    "code": "BITRIX_ERROR",
    "message": "Activity is not found."
  }
}
```

## Errors

| HTTP | Code | Description |
|------|-----|---------|
| 422 | `BITRIX_ERROR` | Activity not found or no permission to delete |
| 403 | `SCOPE_DENIED` | The API key lacks the `crm` scope |
