We have 3 user personas, which has their own login and own cognito user pool. I would like to generate more specific IAM policies based on user groups but I cannot get the user groups information in the authorizer.

Flow remains the same, you authenticate with Cognito User Pool and use token to make calls to API Gateway; Change is, within API Gateway you add a custom lambda authorizer. I understand from this link, we can do it for rest api but want to understand whether we can do it for new http api gateway end point. 1 Published 14 days ago Version 5. What you'd want largely would boil down to your application needs, but Cognito's concepts of scoping credentials, securely getting AWS credentials without embedding resources, a unique identifier for all users, and the concept of authenticated vs unauthenticated users are the most common reasons why one So I am in the process of designing an API Gateway that will power a single page app. I hope the 18h of my life spent on this will "x-amazon-apigateway-authorizer" : { // An API Gateway custom authorizer definition "type" : "token CloudFormation to Configure API Gateway Method to use Cognito Authorizer.
