AWS Lambda integrations

AWS Lambda is a common backend microservice used in microservice applications to provide a serverless backend. If your microservices are mainly written using AWS Lambda, integrating them with API Gateway is a fairly straightforward task. You simply need the name of the Lambda function that your edge API endpoint needs to call as part of the integration, and then add it to the integration.

You may also specify the mappings between the request data and the integration request and the integration response data resulting from the integration. Figure 6-8 shows how a Lambda integration can be specified using the AWS console.
