Build an API Gateway API Using Proxy Integration and a Proxy Resource

As an API developer, you can configure a proxy resource in an API Gateway API to enable a client to access an HTTP back end 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 Configure Proxy Integration with a Proxy Resource.

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.
