How do I implement specific events into google analytics?

How would I Include events to be tracked using Google analytics, I really can't figure this on out, I can't even begin to think about the proper way to do this, any help Would be appreciated.

--for when a player joins, this can be exchanged for any event

game.Players.ChildAdded:connect(function(p)
url = --google analytics form url
game:GetService("HttpService"):GetAsync(url)
end)

I simply got this from the ROBLOX wiki.
