All responses include an HTTP status code and, unless the status code is 204 (No Content), a Content-Type header. Response content depends on the request. Some responses include a document body, some include only a URL, and some are empty.

Response content depends on the requested operation. The response to a GET request is typically the complete representation of an existing object. The response to a PUT or POST request always contains values for the href, name, and id attributes of the object being created or updated. It also contains at most one Task element that you can retrieve to track the progress of the operation. When the Task completes with a status of success, a GET request to the object's href returns all properties of the object. If the Task completion status is not success, the object is in an indeterminate state, and should be deleted.

A vCloud API client can expect a subset of HTTP status codes in a response.

HTTP Status Codes that the vCloud API Returns

Status Code

One or more objects specified in the request could not be found in the specified container.

The user is not authenticated or does not have adequate privileges to access one or more objects specified in the request.

The user 's session has expired.

500 Internal Server Error

503 Service Unavailable

The following HTTP headers can appear in responses to vCloud API requests:

x-vcloud-authorization

An authentication token in the response to a login request. Use this token to authenticate subsequent requests. See Logging In.

X-VMWARE-VCLOUD-REQUEST-ID

If a request supplied an X-VMWARE-VCLOUD-CLIENT-REQUEST-ID header, the response contains an X-VMWARE-VCLOUD-REQUEST-ID header whose value combines the value in the X-VMWARE-VCLOUD-CLIENT-REQUEST-ID with a unique ID. This value is added to every vCloud Director, vCenter, and ESXi log message related to processing the request, and provides a way to correlate the processing of a request across all participating systems. If a request did not supply a X-VMWARE-VCLOUD-CLIENT-REQUEST-ID header, the response contains an X-VMWARE-VCLOUD-REQUEST-ID header with a generated value that cannot be used for log correlation.

X-VMWARE-VCLOUD-REQUEST-EXECUTION-TIME

The execution time, in milliseconds, of the request that generated this response.
