You can use AWS CloudFormation to create an Amazon Cognito user pool and an Amazon Cognito authorizer. The example AWS CloudFormation template does the following:
-
Create an Amazon Cognito user pool. The client must first sign the user in to the user pool and obtain an identity or access token. If you're using access tokens to authorize API method calls, be sure to configure the app integration with the user pool to set up the custom scopes that you want on a given resource server.
Creates an API Gateway API with a
GETmethod.Creates an Amazon Cognito authorizer that uses the
Authorizationheader as the token source.
