S2S postbacks: how to set them up between advertiser, network and partner

What an S2S postback is

A postback is a request one server sends to another when an event happens: a sign-up, a deposit, a sale. Unlike a pixel, it does not depend on the user's browser, so ad blockers and cookie limits do not lose it.

How a conversion travels

1. 1A partner sends a click to your tracking link, and PrimeTrack creates a click_id.
2. 2The click_id goes to the advertiser inside the offer link.
3. 3When the player deposits, the advertiser sends a postback to PrimeTrack with that click_id.
4. 4PrimeTrack records the conversion and sends a postback on to the partner.

Advertiser postback

Give the advertiser a URL like this one. Their system replaces the macros in curly braces with real values:

https://track.your-network.com/api/postback?click_id={click_id}&status={status}&payout={payout}

PrimeTrack also accepts the click ID under the names other trackers use, such as clickid, subid or sub1, so Keitaro, Binom and Voluum setups work without rewriting.

Partner postback

The partner adds their URL in the dashboard and chooses which events to receive. For example:

https://partner-tracker.com/pb?clickid={sub1}&sum={payout}&status={status}&geo={geo}
