Hi Tommy

I have now progressed onto your SDK and have followed the guidelines at [https://marketplace.zoom.us/docs/sd/native-sdks/web](https://marketplace.zoom.us/docs/sd/native-sdks/web)

however your sample code fails because you expect API keys to be 22 characters in length however mine is 36 characters.

“Api key length error, must 22”

Other people have complained about this at

[https://devforum.zoom.us/t/invalid-parameter-websdk-1-7-6/14070](https://devforum.zoom.us/t/invalid-parameter-websdk-1-7-6/14070)

Sorry if some of the above URL’s are incorrect however Google Mail seemingly now does not support text pasting this morning!

Kind Regards, Garry.
