Using API Gateway to obtain tokens with the client credentials grant

Use the client credentials grant flow in API Gateway to authenticate backend services and obtain access tokens for secure, automated API communication.

API Gateway supports the client credentials grant flow, an OAuth 2.0 authorization method for system-to-system communication.

To use this flow, create a backend service authorized application, download its credentials, and use those credentials in an API client to request an access token. The token provides access to protected resources through API Gateway.
