Clarity NDC uses standard HTTP response codes to indicate the success or failure of API requests.
| Code | Reason | Description |
|---|---|---|
| 200 | Success | The request is successful. |
| 400 | Bad request | The server was unable to process the request because of a missing or malformed parameter. |
| 401 | Invalid authentication | The request requires user authentication. A valid authentication token was not provided with the request, so the API could not associate a user with the request. This could mean no token was provided, or the provided token was incorrect (or disabled). |
| 404 | Not found | The server has found nothing matching the Request. Either the request method and path supplied do not specify a known action in the API, or the object specified by the request does not exist. |
| 500 | Internal error | The server encountered an unexpected error, which prevented it from fulfilling the request. |
