  - `request_id` string, required: ID of the request.

## Other responses

- `400`: Bad Request
- `401`: Unauthorized
- `404`: Not Found
- `429`: Rate limited. The provider or Nylas throttled the request. If a provider throttles a request and says how long to wait, the `Retry-After` header gives that number of seconds. When the header is missing, retry with exponential backoff. See [429 rate limit errors by provider](/docs/api/errors/400-response/#429-rate-limit-errors-by-provider).
- `504`: Provider Failure

## Changes

- **2026-09-26** `763d6b969cd7`: 1 info
  - added the optional property `error/provider_error` to the response with the `429` status
