Create a REST API with API Gateway and Lambda | AWS Cloud Computing Tutorials for Beginners

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 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.

@1:14 thanks for showing "The Other Direction" for creating an AWS API Gateway trigger for an AWS Lambda function.
The normal direction most of us are familiar with is via the "Create Trigger" on the Lambda console -- then you choose API Gateway and it will automatically create the "/ANY/" method for you as a convenient API (aka all the methods, not just GET or POST etc.), and as a proxy for Lambda (aka it handles all sorts of property name mapping in the Request and the Response for you, can be confusing when you look at the index.handler "event" arg that is passed, but your way lets you have full control... pros and cons to that of course!

I would love to see another video on this but when using a Private REST API. I’m wrestling with DNS resolution with one right now and I’m sure with a clear walkthrough from you I’d be able to sort it out 😂

This is beautiful. You're beautiful. Loved it.
