Hi Novita! decide.mixpanel.com is a deprecated endpoint. If you're trying to hit the Feature Flag endpoint, the requests should go to api.mixpanel.com/flags (docs here) Can you try that to see if it resolved the issue? If you still get 401s after switching, please open a support ticket directly with an example request (no tokens or secrets), and we can look into it further!
