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.
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
You should be familiar with:
- AWS Lambda basics
- API Gateway basics
The following content can be used to fulfill the prerequisites:
May 12th, 2022 - Updated lab to utilize a Cloud Academy-hosted Linux command-line interface
November 17th, 2021 - Fixed the link to the lambda function complete code listing
January 22nd, 2021 - Updated AWS Lambda lab steps to reflect latest user interface updates
January 10th, 2019 - Added a validation Lab Step to check the work you perform in the Lab
Nov. 15th, 2018 - Lab completely updated including easier to follow instructions, screenshots to match the latest experience, and removal of security warnings in the AWS Console.
