Retrieving Service Endpoints

To access services and resources in the virtual environment, client applications that use the
vSphere Automation
 API must know the endpoints of
vSphere Automation
 and vSphere services. Client applications retrieve service endpoints from the Lookup Service that runs on
vCenter Server
.
The Lookup Service provides service registration and discovery by using the vSphere Web Services API. By using the Lookup Service, you can retrieve endpoints of services on
vCenter Server
. The following endpoints are available from the Lookup Service.
  • The vCenter Single Sign-On endpoint on
    vCenter Server
    . You can use the vCenter Single Sign-On service to get a SAML token and establish an authenticated session with a
    vSphere Automation
     API endpoint or a
    vCenter Server
     endpoint.
  • The
    vSphere Automation
     API endpoint on
    vCenter Server
    . Through the
    vSphere Automation
     endpoint, you can make requests to
    vSphere Automation
     API services such as virtual machine management, Content Library, and Tagging.
  • The
    vCenter Server
     endpoint. In case you want to retrieve service endpoints on a
    vCenter Server
     instance that is part of a vCenter Enhanced Linked Mode group, use the
    vCenter Server
     endpoint to get the node IDs of all linked instances. You can use the node ID of the specific
    vCenter Server
     instance to retrieve service endpoints on that instance.
  • The vSphere Web Services API endpoint and endpoints of other vSphere Web services that run on
    vCenter Server
    .

Workflow for Retrieving Service Endpoints

The workflow that you use to retrieve service endpoints from the Lookup Service might vary depending on the endpoints that you need and their number. Follow this general workflow for retrieving service endpoints.
  1. Connect to the Lookup Service on
    vCenter Server
     and service registration object so that you can query for registered services.
  2. Create a service registration filter for the endpoints that you want to retrieve.
  3. Use the filter to retrieve the registration information for services from the Lookup Service.
  4. Extract one or more endpoint URLs from the array of registration information that you receive from the Lookup Service.
