Outlining a Client for the JSON Protocol
Last Updated December 16, 2024

A client to work with the JSON protocol generally contains the following parts, at minimum.

The basic elements of the URL, including the address of the vCenter Server instance, the service endpoint specifier, and the version specifier.

The credentials with which you authenticate your client session.

Code to GET managed object properties, such as the

ServiceInstance

content, which contains managed object references to singletons, including the

SessionManager

Code to POST requests that invoke methods on managed objects, such as

LoginByToken

A request to fetch the

ServiceInstance

content and extract the

SessionManager

managed object reference.

A request to authenticate the client session with

SessionManager

A request to end the client session.
