You are looking for this one https://xyzscripts.com/solutions/cost-per-action-cpa-ad-network-script leave the full link or people won't know which script you mean. That costs $249 so I assume you looking to pay less. That is why I say the above is a good option.
This one is only $50 https://scriptgod.info/
I forget the name but there was a nice one for $75 it was the only one at that price so if you see one for $75 its probably the one I am thinking about.
