How to secure API Gateway Resources with custom authorization logic
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 quota for your API consumers. IAM is a good choice whenever 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.
