I am using a stream deck and I am trying to find a way to easily control some devices. I saw some tutorials online using webhooks, ifft, and hubitat but I was wondering if there was a way I could trigger a rule or event using a basic url. Is this a possibility?
IE A url link that will turn on my kitchen light or unlock a door when I see my wife on camera.
You'll want to make use of the Maker API and Groups. Create groups of lights that you want to control, and then you can use the Maker API to make http calls to them to adjust.
Alternately, you could also use cloud and local end points in RM as well (as @potts.mike pointed out).
