The Rackspace Ticketing API supports the JSON data serialization format.
The request format and resource version are specified by using the
Content-Type header and are required for operations that have a request body. If
application/json is provided, the latest resource version is used. To avoid unintentional interruptions with your integration, Rackspace recommends specifying a specific version header rather than relying on
application/json, as version updates result in your immediate adoption of the latest version.
You can specify the response format and resource version in requests by using the
Accept header. If no response format is specified, JSON is the default and the latest version is used.
