A Server-to-Server (S2S) Postback<\/strong> is a method used in CPV tracker (CPV Lab<\/a> or CPV One<\/a>) to record conversions through direct communication between servers. Unlike pixel tracking<\/a>, which relies on the user’s browser, S2S postbacks are immune to ad blockers, cookie restrictions, and privacy settings.<\/p>\n<\/blockquote>\n\n\n\n

The workflow is straightforward:<\/p>\n\n\n\n

    \n
  1. A user clicks<\/a> a campaign<\/a> link, and CPV tracker generates a unique Click ID<\/a><\/strong>.
    <\/li>\n\n\n\n
  2. This Click ID<\/a> is passed to the affiliate network<\/a> in the Offer<\/a> URL.
    <\/li>\n\n\n\n
  3. When the user completes a conversion<\/a>, the network’s server calls the CPV tracker (CPV Lab or CPV One) postback URL, passing back the Click ID<\/a> and payout details.
    <\/li>\n\n\n\n
  4. CPV tracker (CPV Lab or CPV One) matches the conversion<\/a> to the original click, updating reports with revenue<\/a>, cost<\/a>, and profit.
    <\/li>\n<\/ol>\n\n\n\n

    A typical postback URL looks like this:<\/p>\n\n\n\n

    https:\/\/yourtracker.com\/postback?subid={clickid}&revenue<\/a>={payout}<\/p>\n\n\n\n

    In this example, {clickid} is replaced by the actual Click ID<\/a> and {payout} by the payout value.<\/p>\n\n\n\n

    CPV tracker (CPV Lab<\/a> or CPV One<\/a>) simplifies S2S setup by providing network templates<\/strong>. These templates include pre-set tokens and macros for many popular affiliate networks. All you need to do is paste the postback URL into your affiliate network<\/a>’s settings.<\/p>\n\n\n\n
