Just started to test the API, followed the instructions given at [https://marketplace.zoom.us/docs/api-reference/testing-zoom-apis](https://marketplace.zoom.us/docs/api-reference/testing-zoom-apis) (created an app and set the redirect URL to [https://next.stoplight.io/oauth/callback/success](https://next.stoplight.io/oauth/callback/success)). I then headed over to zoom-api/users/users to test using the widget, successfully obtained an access token, but sending the request just resulted in showing an error message: “The API did not return a response. Is it running and accessible? If you are sending this request from a web browser, does the API support cors?”

What could be up there?  
Thanks, Max

Ooops, must have set the “Send requests directly from the browser (CORS must be enabled)”-checkbox by mistake. All good now.
