Do you have any documentation for custom query parameters in zoomus and zoommtg protocols? Is it publicly supported?  
For example, I want to use like these:  
zoommtg://zoom.us/join?confno=123456789&pwd=xxxx&uname=CustomName  
zoomus://zoom.us/join?confno=123456789&pwd=xxxx&&uname=CustomName

Hi @andrew11,

Thank you for reaching out about this—I’m afraid this is not officially supported.

If you wish to pass information in the request URL such as a display name, we suggest leveraging [registration](https://support.zoom.us/hc/en-us/articles/211579443-Setting-up-registration-for-a-meeting) and retrieving custom join\_urls for your registrants via this endpoint:

> **[List meeting registrants - Meetings - Zoom API - API Reference](https://marketplace.zoom.us/docs/api-reference/zoom-api/meetings/meetingregistrants)**
>
> A host or a user with admin permission can require registration for a Zoom meeting. Use this API to list users that have registered for a meeting.
> Scope...

Thanks,  
Will
