Is it possible to use sequence: Cognito Authorizer and Lambda Athorizer?

Hi Oleg :)

I think this answer outlines well the options for role based authorizations: https://repost.aws/questions/QUpYtLZR5wQVqOSWI4BcblQQ/rbac-for-api-gateway-endpoints-using-cognito-user-groups.

Hope it helps

Hi, @Oleg.

I understand that "AWS Gateway" is "API Gateway".

You cannot set multiple authorizers in combination in API Gateway.
So you have to implement your custom logic in the Lambda authorizer.

Validate Cognito's JWT in Lambda and check for the target user pool. Then perform custom processing.
