Troubleshooting for Knox Deployment Program

The Knox Deployment Program Reseller API uses the conventional HTTP response codes to indicate the success or failure of a request. A 2XX response code indicates success, a 4XX response code indicates a client-side error due to the request inputs, and a 5XX response code indicates a server-side error. It also includes custom error codes that are specific to Knox Deployment Program. In addition, errors will contain a JSON response body with more information about the error:
