Protect AWS API Gateway Endpoints using API Keys

Overview

AWS API Gateway offers various ways to protect API endpoints, most recently AWS announced Private Endpoints which are only accessible from VPC. In addition to that, you can protect APIs using the following methods

  • Custom Authorizers
  • API Keys
  • Client Certificates
  • Or a combination of these

In this post, we will cover the API keys method only. Using API keys you can also create Usage Plans which allows you to enable Throttling and Quota on the APIs.

Example

In this example, we have an AWS lambda function which is exposed using the AWS API Gateway endpoint, we will protect the endpoint using API keys and test it using Postman tool. The API is called My API with a resource called hello and a GET method calling Lambda function hello-lambda as shown on the slide.
