Hi @boston85719 ,
It’s okay if they’re using the development credentials because I’m assuming the testing you’ve done where you are unable to reproduce the same error is also with the development credentials (please correct me if I’m wrong!).
Can you please send me an email a link to this thread with your app credentials, full request and response to developersupport@zoom.us? I will inquire as to why they’re getting “user:write” as a required scope when it is not available to add.
Thank you,
Gianni
