Build an API Gateway API as an HTTP or Lambda Proxy

As an API developer, you can configure a proxy resource in an API Gateway API to enable a client to access an HTTP backend or to call a Lambda function following various routes with a single integration setup on a catch-all ANY method. For more information about the proxy resource, ANY method and proxy resource integration types, see Set up Proxy Integration.

This tutorial describes how to build and test two APIs with proxy resources, one for an HTTP back end and the other for a Lambda function. To follow the instructions, you must have signed up for an AWS account. For more information about signing up for AWS, see Getting Started.
