A developer is creating a new REST API by using Amazon API Gateway and AWS Lambda.The development team tests the API and validates responses for the known use cases before deploying the API to the production environment.The developer wants to make the REST API available for testing by using API Gateway locally.

Which AWS Serverless Application Model Command Line Interface (AWS SAM CLI) subcommand will meet these requirements?

Sam local invoke

Sam local generate-event

Sam local start-lambda

Sam local start-api

Explanations:

sam local invokeis used to invoke a specific Lambda function locally with an event payload. It is not meant for testing an API Gateway endpoint.

sam local generate-eventis used to generate sample event payloads for various AWS services, which can be useful for testing, but it does not start a local API Gateway.

sam local start-lambdastarts a local Lambda endpoint for invoking Lambda functions, but it does not start an API Gateway to expose HTTP endpoints for testing.

sam local start-apiis the correct command to run a local API Gateway that allows the developer to test the REST API endpoints defined in the SAM template. This command serves the API locally and simulates API Gateway behavior.
