When trying to connect with Zoom JS SDK, I ran into an issue where my error was Join Parameters not valid. So I asked around the forum and was told to email firstname.lastname@example.org with my token. After about 26 hours I got a response:
Happy to help.
Can you please confirm that you are using the JWT App Client ID and not the SDK App Client ID to generate the signature?
To which I responded that I was using the JWT app client id and not the SDK App client ID. That was on May 20th. I followed up again on May 21st and May 22nd. It is now May 28th and I have not heard anything back from Zoom. Super disappointed in the lack of support for developers who want to work with Zoom.
