AWS API Gateway to Lambda Tutorial in Python | Build a REST API

API Gateway is a powerful AWS service that allows you to host a REST endpoint that is backed by an AWS service (in this case, Lambda). In this video, I show you how to create a REST Endpoint using API Gateway. Requests are served by a Lambda Function (as opposed to a traditional server). I start by creating a Lambda function and coding up a basic handler using Python (code below). From there, I create a API Gateway resource that acts as a publicly facing REST Endpoint. I continue to hook up the endpoint to the previously created Lambda function. Finally, I test the configuration by invoking the REST endpoint through my browser and verify my Lambda was serving the content back.

As an AWS engineer I have to say, very good tutorial video. Why such a channel only has 21k sub??? For begineers, your videos are better than our official ones.

Wow. Short, complete, accurate and useful. You are remarkably good at making instructional videos. Thank you.

[vojtechkaiser]

Great work! Appreciate you showing the event structure right at the beginning which is usually skipped by many.
