Zoom Client URL Schemes

When integrating your application with Zoom, you can use a URL protocol (ex: zoomus:) instead of https:// to start or join a meeting or Zoom Phone call from a Zoom Client directly. This will prevent users from being brought to a browser window before starting or joining a meeting.

If a user does not install the Zoom Client before starting or joining a meeting, a pop-up window will detect your current installation and recommend to install or update the client.
