* If the client sends a <code>Content-Type</code> other than <code>application/json</code> on a POST, PUT or PATCH request, the service will respond with a <code>415</code> (Unsupported Media Type) [[#Error codes and responses|error code]].
* If the client sends invalid JSON, the service will response with a <code>400</code> (Bad Request) HTTP [[#Error codes and responses|error code]] and a descriptive error message within the error object.
* When returning a <code>401</code>, a proper <code>WWW-Authenticate</code> header must be sent as well as documented in [http://tools.ietf.org/html/rfc7235#page-7 RFC7235 (or earlier HTTP 1.1/1.0 RFCs).
Unless otherwise noted, the [http://tools.ietf.org/wg/httpbis/ HTTPbis RFCs] always apply.
