Postback URL

A postback URL is the server-to-server message that closes the tracking loop: when a referred player registers or deposits, the operator’s platform calls a pre-agreed URL on the tracking side, passing the click ID and conversion details as parameters.

Why it beats pixels

Because the call happens between servers, it survives ad blockers, cookie deletion and iOS privacy restrictions that kill client-side pixels. In iGaming, where a conversion can happen days after the click and player value accrues for years, postbacks are the standard — pixels are the fallback.

Typical parameters

clickid, goal (reg/FTD/deposit), amount, currency, player_id (hashed). Test every parameter in staging before launch; a malformed postback is the #1 cause of “missing conversions” disputes with affiliates.
