Discovery Document

  • Discovery documents describe the surface, access methods, and structure of API requests and responses for specific API versions.

  • These documents provide API-level details including descriptions, resource schemas, authentication scopes, and methods, focusing on the RESTful invocation method.

  • The discovery.apis.list method can be used to retrieve a list of all supported APIs and their REST-based discovery document URLs.
Discovery documents are available for specific versions of most APIs. Each API's Discovery Document describes the surface of the API, how to access the API and how API requests and responses are structured. The information provided by the discovery document includes API-level properties such as an API description, resource schemas, authentication scopes, and methods.
