This may be far from obvious, but another reason of seeing "Forbidden" error when using AWS API Gateway may be calling incorrect URL that does not correspond to any deployed API method. It can occur if you're actually hitting wrong URL (e.g. instead of calling https://9999xx9x99.execute-api.us-east-1.amazonaws.com/dev/users (note dev stage before users) you called https://9999xx9x99.execute-api.us-east-1.amazonaws.com/users (no stage). You'd expect to get 404, but you'll get 403.

BTW: after you make a deployement to https://9999xx9x99.execute-api.us-east-1.amazonaws.com/dev/users calling https://9999xx9x99.execute-api.us-east-1.amazonaws.com/user (note singular noun form here) you'll get… 403 as well, but with "Missing Authentication Token" message!
