Request and response types#

The Rackspace Cloud Networks API supports JSON data serialization format.

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

The syntax for the Content-Type header is:

Content-Type: application/json

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.

You specify a json response format by using one of the following methods:

• Accept header. The syntax for the Accept header is:

  Accept: application/json
  

• Query extension. Add the .json extension to the request URI. For example, the .json extension in the following URI request specifies that the response body is returned in JSON format.

  POST /v2/010101/servers.json
  

If you do not specify a response format, JSON is the default.
