For ten years, affiliate link tracking depended on 3rd-party cookies and blind faith. Now, with Safari ITP, Mozilla's ETP and Google's privacy sandbox reshaping the browser environment, that model silently fell apart.
What replaced it is server-to-server (S2S) setup: a distinct click ID injected into the advertiser's order flow, then sent back through a postback URL the moment a conversion is registered. No cookie, no pixel dependence, no silent revenue leakage.
Serious affiliate tracking software is no longer a link redirector with a admin panel bolted on.
