Request and response types
The Rackspace Metrics API supports JSON data serialization formats.
Format - JSON
Accept Header - application/json
Query Extension - .json
Default - yes
Specify the request format by using the
Content-Type header, which is required for operations that have a request body.
You can specify the response format in requests by using the
Accept header or by adding a
.json extension to the request URI. If no response format is specified, JSON is the default response format.
