+
+## Azure REST API version, endpoint, and HTTP client parameters
+
+This resource interacts with api versions supported by the resource provider.
+The `api_version` can be defined as a resource parameter.
+If not provided, the latest version will be used.
+For more information, refer to [`azure_generic_resource`](azure_generic_resource.md).
+
+Unless defined, `azure_cloud` global endpoint, and default values for the HTTP client will be used.
+For more information, refer to the resource pack [README](../../README.md).
