Service APIs
An extension service can define its own request and response body elements if it needs to. API schema files
can be specified as part of service registration or can be added later. Schema files can reside at any location
that is reachable by the extension service.
Support for Idempotent Operations
Most requests to extension services can include an operationKey attribute, which is a string meant to uniquely
identify the operation so that if it is invoked multiple times, the result will be the same as if it had been invoked
only once. The following types support use of the operationKey attribute:
n
AclRuleType
n
ApiDefinitionType
n
ApiFilterType
n
FileDescriptorType
n
ResourceClassActionType
n
ResourceClassType
n
ServiceLinkType
n
ServiceResourceType

Summary of vCloud API Extensibility Requests
vCloud API extensibility requests allow you to develop extension to vCloud Director.
n
API-URL is a URL of the form https://vcloud.example.com/api.
n
id is a unique identifier in the form of a UUID, as defined by RFC 4122.
IMPORTANT Request URLs are always available in Link elements contained by the representation of the object
on which they operate. URL forms shown here are for reference purposes only. Although URLs have a well-
known syntax and a well-understood interpretation, a client should treat vCloud API request URLs as opaque
strings. The rules that govern how the server constructs these strings might change in future releases.
This summary may not cover all requests in this category. For the complete list of requests, along with detailed
information about input and output types, see the Operations lists in the schema reference.
