Hey @russliu,

Thank you for reaching out to the Zoom Developer Forum. It looks like you’re using an SDK key and secret. When it comes to the [Web SDK](https://marketplace.zoom.us/docs/sdk/native-sdks/web#zoom-web-sdk), make sure that you are using a [JWT App](https://marketplace.zoom.us/docs/guides/auth/jwt)’s API Key and Secret.

Let me know if that helps.

Thanks,  
Max
