I created Cognito Authorizer with API Gatwway and need to test. If I used the access token with Cognito Authorzer, it is failing. But If I called the api gateway with the access token, it works. I want to test the Cognito Authorizer it self.
When you test Cognito Authorizer itself, then you have to use ID token, not the Access token . I faced the same issue and took ages to figure out.
This video could be helpful as it shows step by step "Secure API Gateway using Cognito" https://www.youtube.com/watch?v=9crTLAT_4uY
