Postback URLs Explained: The Key to Accurate Affiliate Tracking

What Is a Postback URL?

A postback URL (also called a server-to-server pixel or S2S pixel) is a tracking method where conversion data is sent directly from the merchant's server to your tracking platform's server — no browser, no cookie, no JavaScript required. This makes it immune to ad blockers, iOS privacy restrictions, and browser cookie limitations.

ClickMagick supports postback URLs natively, making it the preferred tracking solution for serious affiliate marketers who need 100% accurate conversion data.

How to Set Up Postback Tracking

In ClickMagick, generate your unique postback URL from the tracking settings. Provide this URL to your affiliate network or merchant. When a conversion occurs, the merchant's server pings your ClickMagick postback URL with the transaction details — commission amount, order ID, and the click ID that drove the sale.

Why Postback Beats Pixel Tracking

Pixel-based tracking (JavaScript snippets) fails when users have ad blockers, when browsers restrict third-party cookies, or when the conversion happens in a different browser session. Postback tracking has none of these limitations — if the sale happens, you track it, period.
