415 ("Unsupported Media Type") must be used when the media type of a request"s payload cannot be processed

[manuelmerkel]

Describtion

The 415 error response indicates that the API is not able to process the client’s supplied media type, as indicated by the Content-Type request header.

Example

A client request including data formatted as application/xml will receive a 415 response if the API is only willing to process data formatted as application/json.
