# API Error Responses

This guide explains the HTTP status codes and messages returned by the API when a request fails.

When a request fails due to request errors, an error response message is returned in JSON format. The error response message includes a unique error code for the endpoint, an HTTP response message, and an HTTP response code. When enabled, the response contains HATEOAS links.

### Example Response
