Veeam Virtualization Extensions Service (VES) exposes its entities through an application programming interface (API) based on the Representational State Transfer (REST) architecture style. The VE Service REST API allows developers to query information about VES entities and perform basic operations with these entities using HTTP requests and standard HTTP methods.

The VE Service REST API is a operation-oriented application programming interface that relies on the client-server model. The client makes a request to the server; the server processes the request and returns a response with a conventional HTTP response code, HTTP response headers and a response body in the JSON format (by default).

The VE Service REST API is served over HTTPS. To ensure data privacy, unencrypted HTTP is not supported.
