Hey @officialmakkar,

I am suspecting that the JWT payload may be generated incorrectly. To verify this, can you create a JWT through [JWT.io](http://JWT.io) and hardcode it into your application to see if this above code is causing the issue? Instructions for doing so can be found here: ["auth sdk failed" when running zoom sdk demo - #7 by Michael\_Condon](https://devforum.zoom.us/t/auth-sdk-failed-when-running-zoom-sdk-demo/37448/7)

Thanks!  
Michael
