Postback (S2S tracking)
A server-to-server (S2S) HTTP request sent from the advertiser's system to the ad-tracking platform when a tracked conversion occurs (sign-up, deposit, sale). Unlike pixel-based browser tracking, postback works without cookies or browser sessions — it carries a click ID parameter that ties the conversion back to the originating ad click. Telegram-ad buyers using affiliate networks rely on postback to attribute revenue to specific creatives and channels.
