Error 0021

HTTP Error code

400

Description

The request could not be decoded. This error occurs when either the request body does not match the specified content type and content encoding, or the query contains invalid characters.

Remedy

Ensure the Content-Type and Content-Encoding headers match the body encoding and that any query string escape sequences contain valid UTF-8 encoded characters.

Error Responses

All web service API's can response with JSON objects, however some legacy API's return XML/HTML error responses by default.

Api's will return JSON errors if a request contains the "Accept" header with a valid json content type, "application/json" or "text/json"

We strongly recommend the use of the "Accept: application/json" on all web service requests to ensure that all error responses are returned in a consistent format.

JSON Error Response

The JSON response object always contains the two parameters, error and request. These objects are further detailed below.
