I would like to integrate Tapfilliate or Post Affiliate Pro or something similar so that I can give affiliates a link and track conversions from that link so I can pay the affiliate automatically or manually.
Any help is appreciated!
That is not really a code issue for which this forum should be used for.
You are better suited going through Wix Support and asking them about Wix Affiliate Marketing there.
