Description

Lab Overview

Amazon API Gateway offers several native authorization mechanisms, such as managed API keys, IAM Roles, and custom authorizers. API Keys (with the help of Usage Plans) can help manage custom throttling and quotas for your API consumers. IAM is a good choice when your consumers require access to AWS resources and you need to manage permissions on a per-user basis. However, custom authorizers give you much more flexibility. With custom authorizers, you can implement any 3rd-party integration and generate very granular authorization policies.

In this Lab, we will learn how to implement a custom authorizer in AWS Lambda to secure your API Gateway Resources.

Lab Objectives

Upon completion of this Lab you will be able to:

  • Understand API Gateway request authorization
  • Explain the advantages of using custom authorizers in API Gateway
  • Create Lambda functions to implement custom authorizers using AWS Lambda blueprints
  • Test custom authorizers using methods appropriate at each stage of deployment

Lab Prerequisites

  • AWS Lambda basics
  • API Gateway basics

The following content can be used to fulfill the prerequisites:
