# Verify API access

AMS uses the AWS API, with some AMS-specific operations that you can read about in the [AMS API Reference](https://docs.aws.amazon.com/managedservices/latest/ApiReference-cm/index.html).

AWS provides several SDKs that you can access at [Tools for Amazon Web Services](https://aws.amazon.com/tools/). If you don’t want to use an SDK, you can make direct API calls. For information on authentication, see [Signing AWS API Requests](https://docs.aws.amazon.com/general/latest/gr/signing_aws_api_requests.html). If you are not using an SDK, or making direct HTTP API requests, you can use the AMS CLIs for Change Management (CM) and SKMS.
