How to open a Zoom link in a non-browser app without being prompted? URLs have long been the domain of web browsers, but some apps challenge this assumption by asking your browser to open a link in their dedicated app.

Problem: Safari Keeps Asking Permission

For example, I use Zoom.us, a videoconferencing service. They give me a link associated with my conference call that's easy to throw into a calendar invite, like https://ibm.zoom.us/j/9747900418. When I click the link, my browser opens it, authenticates me, and asks me permission to open the link in Zoom.us.app, which I've already installed.



After opening hundred of meetings this way, I'm sick of it asking me permission. I want Safari to remember that it's allowed to open zoom.us/* links in Zoom.us.app.  

What I've Tried

Under Safari > Preferences > Websites, I escalated privileges for Zoom-related items:


General > Auto-Play > ibm.zoom.us was "Stop media with sound"; set to "Allow Auto-Play"
Plug-ins > Zoom Launcher 3.0.1 > ibm.zoom.us was "Ask"; set to "On"
Plug-ins > Zoom Launcher 3.0.1 > support.zoom.us was "Ask"; set to "On"


This had no effect. So how can I get Zoom links to open correctly?
Have you tried rewriting the URL so that it uses the zoommtg:// protocol?
You rewrite a URL of this format ...
https://us02web.zoom.us/j/123456789?pwd=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

... like this:
zoommtg://zoom.us/join?confno=123456789&amp;pwd=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

If you have the Zoom app/client installed on a Mac, using URLs with the zoommtg protocol should cause them to open directly in the Zoom app, no matter where the URL is clicked from. Personally, I use this URL format in the Notes field of Calendar events, and it works great.
