Trying to start a meeting from a button in my workplace app.  
Using the meeting join link  
**Description**  
I have an app that manages meetings, and I added a “Start as Host” button to start the meeting.  
**Error?**  
During the meeting flow, the call to the marketplace link throws this error.

If you ignore it, it will go on to launch the meeting correctly.

Shouldn’t a call here be already whitelisted by Zoom, or do I have to whitelist it in every app???

**How To Reproduce**  
Create a Zoom join link.

Can you check the Zoom App Domain Allow list and see if everything required is whitelisted that my first guess

@expertswho can you get back to Kwaku regarding whitelisting?
