The Cloud Authentication API supports both the JSON and XML data serialization
formats. The request format is specified 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 by adding an
.xml or .json extension to the request URI. Note that
it is possible for a response to be serialized using a format different from the
request. If no response format is specified, JSON is the default. If conflicting
formats are specified using both an Accept header and a query
extension, the query extension takes precedence.
| Format | Accept Header | Query Extension | Default |
| JSON | application/json | .json | Yes |
| XML | application/xml | .xml | No |
