OK I found the post http request, problem is it does not seem to be working anymore.

I entered http://localhost:8088/api/?Function=SetText&Input=1&SelectedIndex=4&Value=%2b%3d1
This "should" add +1 to the home score in the first scoreboard in vmix, works fine in a browser, but not in companion.

Update, changed localhost in the url to my local IP address, and it started to work, is it supposed to be like this?

Got it going well now.
