The world runs on APIs (application programming interfaces) these days, and it’s likely that you’ll need to build APIs for your own application, or for others to consume.

In AWS, it’s common to create Lambda functions to do a very specific task (more in this video if you’re interested: youtu.be/3Ar1ABlD_Vs). But those Lambda functions aren’t going to be exposed to the outside world. Instead, you’d want the requests to go to an API endpoint, which will then call Lambda. And API Gateway is what allows you to do that.

In this hands-on tutorial, we’ll build a simple “hello world” Lambda function, and then create an API Gateway GET method that calls it. And be sure to stick around to the end where I’ll show you how to delete the resources.
