Question

A developer is building a serverless REST API using AWS SAM. The API consists of an Amazon API Gateway front end and several Lambda functions. Before deploying to a shared test environment, the developer wants to send HTTP requests to the API endpoints from a local browser and a REST client on their laptop to verify routing and response formatting, without deploying anything to AWS. Which SAM CLI command should the developer use?

Accepted Answer

sam local start-api to emulate the API Gateway endpoints locally and route HTTP requests to the Lambda functions

Answer

sam local invoke to directly invoke a single Lambda function with a JSON event file

Answer

sam local generate-event apigateway to create a mock event and pipe it to the deployed API

Answer

sam deploy --guided to push the stack to a test account and then curl the API Gateway URL
