Postback URL Builder

A postback URL is an address your tracker exposes so an affiliate network can report a conversion server-to-server. When a conversion fires, the network calls that URL with the click ID it originally received, and your tracker matches it back to the click that produced it.

A pixel fires in the visitor’s browser, so it breaks with ad blockers, cookie restrictions and cross-domain redirects. A postback is a server-to-server call between the network and your tracker, so nothing depends on the browser — which is why it is the standard for affiliate conversion tracking.
