📝 Walkthrough

Walkthrough

The quick-start guide now uses a RandomUUID REST API instead of the previous HelloWorld mock API. It documents creating and publishing the API with the /uuid context and helper endpoint, subscribing through the Developer Portal, generating an access token with the customer secret, and invoking the API. The expected response now contains a randomly generated UUID.
