Summary

Summary

In this workshop, you:

• Expose the Lambda functions to the internet as a RESTful API by using Amazon API Gateway (instead of using function URL as in previous workshop).

Because you’re using the same Lambda functions as in previous workshop, you need to:

• Use Lambda non-proxy integration and ensure that input to the Lambda function is supplied as the integration request payload.

In other words, you need to:

• Map any input data the client supplied as request parameters into the proper integration request body.

  E.g. From /users/{userId} path to { "id": "$input.params('userId')" } body.

• Translate the client-supplied request body into a format recognized by the Lambda function.
