Postback Url: What It Is, Key Features, Benefits, Use Cases, and How It Fits in Affiliate Marketing
A **Postback Url** is a server-to-server tracking method used to confirm that a desired action (like a purchase, signup, or deposit) happened after a click. In **Direct & Retention Marketing**, this matters because lifecycle campaigns depend on clean, timely conversion data to trigger onboarding, segmentation, suppression, win-backs, and LTV optimization. In **Affiliate Marketing**, it’s one of the most common ways to attribute conversions to the right publisher, campaign, and click—without relying solely on browser-based tracking.
