I have integrated zoom OAuth with my web application. It was working fine but now when I join meeting through my web app it shows Invalid Signature Error. Any help on this would be highly appreciated.

Thanks!

Hey @arttbusinessschool42,

Can you please share a your [Web SDK signature](https://marketplace.zoom.us/docs/sdk/native-sdks/web/essential/signature) for a test meeting to [developersupport@zoom.us](mailto:developersupport@zoom.us) so I can help debug?

Thanks,  
Tommy

Hey @arttbusinessschool42,

Is the meeting owned by the same Zoom account as the JWT App? Could you provide the account # of the JWT App owner and the account # of the meeting owner?

Thanks,  
Tommy
