## Other responses

- `204` — Server has successfully fulfilled the request and there is no additional information to send back.
- `400` — Error caused by the client app, e.g. in case of malformed request or invalid identifier of a resource. In most cases, such an error signifies a bug in the client app (consumer of the API).
- `401` — Error caused by usage of invalid ClientToken, AccessToken, or you may not have the necessary permission to use the endpoint.
- `403` — Server error that should be reported to the end user of the client app. Happens for example when the server-side validation fails or when a business-logic check is violated.
- `408` — Error caused by heavy request that takes too long to process (typically tens of seconds). To get around this, request data in smaller batches. For more information, see [Request timeouts](https://mews-systems.gitbook.io/connector-api/guidelines/requests#request-timeouts)
- `429` — Error caused by too many requests sent in a given amount of time. Response contains `Retry-After` header indicating how long the user agent should wait before making a follow-up request. For more information, see [Request limits](https://mews-systems.gitbook.io/connector-api/guidelines/requests#request-limits).
- `500` — Unexpected error on the Mews side. This may be due to a software fault. If such a situation occurs, the error will be logged and the development team notified, however you can raise an issue through GitHub on our [documentation repository](https://github.com/MewsSystems/gitbook-connector-api).
