Veeam Availability Orchestrator REST API Reference
This REST API reference lists types of VAO entities, and contains description of collections and resources which stand for these entities. Every resource has a JSON object model and includes application data and REST API metadata. Application data is represented by properties associated with VAO entities. REST API metadata is represented by properties specific to the REST API, such as resource IDs, URLs and relationships. The reference also includes methods that represent operations available for a resource or collection.
To learn what method-implemented operations you can perform with VAO entities, and how to control and sort the data that the REST API returns, see the REST API Reference.
