🤔 A way of understanding all the AWS lies.

The structure of the events from CloudTrail are similar to responses seen when using boto3. Boto3 is powered by the botocore library. The botocore library contains a data directory that describes the API calls (requests and responses). This library allows you to interact with the data directories of botocore to see the API request and responses. This is to help you write custom AWS Config rules and or CloudCustodian policies.
