  title: VMware vSphere Automation REST Clusters Session API
  description: RESTful API for managing VMware vSphere virtualization platform resources including virtual machines, hosts, datastores, clusters, networks, and related infrastructure. The vSphere Automation API provides modern REST endpoints for vCenter Server operations using JSON payloads and session-based or OAuth authentication. This API supersedes the legacy SOAP-based vSphere Web Services API for most automation use cases.
