I followed the Quick start to run the demo from here -\> [https://github.com/zoom/sample-app-web](https://github.com/zoom/sample-app-web) , and when i enter the meeting room number is 123 and password is 123, and then click “join”, the error shows “The meeting number is not found.” What should I do?

Hey @kleininmelbourne,

You must use a real Zoom meeting number. Create a meeting [here](https://zoom.us/meeting) and then use that meeting number in the Web SDK.

Thanks,  
Tommy

Hi tommy,

I follow your step and create a meeting, and then there is still error.

It’s said: Signature is invalid.

How should I do next stage?

Hey @kleininmelbourne,

Please share your signature to [developersupport@zoom.us](mailto:developersupport@zoom.us) so I can debug it.

Hey @kleininmelbourne,

You are using your SDK App to generate the signature. You need to use your JWT App credentials instead.

Thanks,
