Hey @umarzaman_1,

As our OAuth docs state, you cannot call the Zoom API from the client side. You can use server side code like Node.js to make calls to the Zoom API.

Thanks,
Tommy

Thanks for your reply Tommy. I was able to achieve it using RestSharp client in Webapi 2.0.

Hey @ofd.aws96,

The majority of APIs require server side or else you will get CORs errors.

Please educate here on the topic:

Thanks,
