Request and response types

The Rackspace Cloud Queues API supports JSON data serialization formats.

The request format is specified by using the Content-Type header and is required for operations that have a request body.

The response format can be specified in requests either by using the Accept header or adding a .json extension to the request URI. A response can be serialized using a format that is different from the request. If no response format is specified, JSON is the default. If conflicting formats are specified by using both an Accept header and a query extension, the query extension takes precedence.
