The vCloud Air Platform APIs follow an API version scheme to ensure standardization throughout the API surface and to provide backward compatibility with future releases.

To specify the API version for content negotiation, include the vCloud Air Platform APIs version in the Accept header as an extension parameter (;version=5.7).

The API versions the entire information model except for the media classes. (The media class for a resource is optional and does not include versioning information.)


If you specify version=* in the Accept header, the API uses the latest API version.

When omitting the version from the Accept header, the API performs the operations by using the most recent API version supported for the vCloud Air Platform APIs.

In HTTP responses, the API returns the version in the Content-Type header as an extension parameter.
