# Status Codes and Errors

The Digital Identity Management server responds to all API requests with standard HTTP status codes. Should the request fail (or be denied) for any reason, then the response also includes JSON payload with a Digital Identity Management-specific business code and message.

See the following topics this section:

* [HTTP Status Codes](r_httpStatusCodes)

* [Digital Identity Management Business Error Codes](r_businessErrorCodes)

* [Java Spring Error Codes](r_JavaSpringErrorCodes)

* **[HTTP Status Codes](../topics/r_httpStatusCodes)**

* **[Digital Identity Management Business Error Codes](../topics/r_businessErrorCodes)**\
  A Digital Identity Management business error code (or just "business code") is returned in the body of a failed or denied API request. In most cases, the business code is accompanied by a human-readable message that describes the issue. Known status codes are listed below and grouped according to the HTTP status code that the business code accompanies.
