vSphere Automation API for REST
The vSphere Automation SDK for REST was discontinued for vSphere 7.0, as it says at this Github link.
You can still make REST API calls for vSphere Automation (vAPI) with the help of normal REST programming tools such as Postman or Swagger. API reference guides are provided below.
For information about remaining vSphere Automation SDKs, see the VMware vSphere Automation SDKs Programming Guide below, and refer to vSphere Automation SDK pages for Python and Java. The VMware vCenter Server Management Programming Guide documents a subset of vAPI that covers operations specific to vCenter Server. For information about traditional vSphere API calls when vAPIs are not available, refer to the vSphere Management SDK.
