  title: AWS Cloud Control Change Sets API
  description: AWS Cloud Control API provides a uniform set of five API operations to create, read, update, delete, and list (CRUDL) supported cloud resources. It offers a standardized way to manage AWS and third-party resource types available in the CloudFormation Registry, without needing to learn each individual service API. You specify the resource type and a JSON blob of desired state, and Cloud Control API handles the rest.
