Hi @ricky ,

Thanks for reaching out. Please send an email to [developersupport@zoom.us](mailto:developersupport@zoom.us) with a link to this thread. In that email, please include the token URL that you’re using as well as the authorization header. I’ll use that to investigate further.

Best,  
Gianni
