Hi @grassking,

Thanks for using the Zoom SDK. The error code indicates that your JWT token is invalid. Are you using the SDK key/secret to generate the JWT token? Could you provide a sample of your JWT payload(without SDK key)?

Thanks!

Hi @grassking,

Thanks for the reply. Based on the screenshot, it seems like the timestamp is incorrect, the unit of the JWT timestamp should be in seconds, using milliseconds will result in error.

Hope this helps. Thanks!
