Here's a sample SAM application that provides the resources to integrate Amazon API Gateway's REST API to AWS Step Functions' Synchronous Express Workflow. And to add to that, it also includes API key configuration, passing the API Key to the Step Function execution. The application also provides mapping templates to help in input and output data modeling for the API.

• AWS Account
• Configuring AWS Credentials
• SAM CLI

Use the "guided" flag while deploying the SAM application for the first time.

sam deploy --guided
