What is S2S Postback?
S2S Postback (Server-to-Server Postback) is a method used in digital advertising to track conversions, leads, or sales directly between servers, without relying on a user’s browser. It works by enabling advertisers to communicate directly with an ad network or tracker’s server to verify a user action, bypassing browser-related issues such as ad blockers and cookie restrictions, ensuring precise, real-time tracking.
