Create and Deploy a REST API with Amazon API Gateway

Lab overview

Amazon API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale. REST APIs in API Gateway offer full API management features, including API keys, throttling, and usage plans.

In this lab, you will build a REST API from scratch using Amazon API Gateway with AWS Lambda proxy integration. You will create API resources and methods, enable Cross-Origin Resource Sharing (CORS) to support browser-based clients, deploy the API to a stage, and test your endpoints using curl from the command line.

By the end of this lab, you will understand the end-to-end workflow of creating and deploying a REST API with API Gateway, including how resources map to URL paths, how methods define allowed HTTP operations, and how stages enable versioned deployments.

Objectives

Upon completion of this intermediate level lab, you will be able to:

  • Create a REST API in Amazon API Gateway with resources and methods
  • Configure Lambda proxy integration to connect API methods to a backend function
  • Enable CORS on API Gateway resources to allow cross-origin requests
  • Deploy an API to a stage and test endpoints using curl

Who is this lab for?

This lab is designed for:

  • Cloud engineers learning to build serverless APIs on AWS
  • Solutions architects preparing for the AWS SAA-C03 certification
  • Developers who want hands-on experience with API Gateway REST APIs
