Has something changed with API Gateway? Now get 401 Unauthorised...

Question

HI,

All API gateway called either through Postman or Unity are now giving 401 unauthorised to endpoints which were working fine. Nothing has been changed on my side which leads me to think AWS has changed something, For example, using an POST method API with a Cognito User Pool Authorizer worked fine with a username and password through Unity and Postman. Now they don't.

Thanks!

Bhav

Hello,

As you said you changed anything., this means using the same HTTP method, the same structure of the url, payload, etc? And not changed anything in the user pool?

You have some further logs from CloudWatch to check?

This [documentation page](https://aws.amazon.com/pt/premiumsupport/knowledge-center/api-gateway-cognito-401-unauthorized/) also is a great way to start to understand.
