The problem with cookies
Safari, Firefox and consent banners shorten or block cookies. The result: sales are not attributed to any partner, commissions are lost and partners lose trust.
How S2S tracking works
On the click, the visitor receives a unique click ID. After the purchase, your server reports the conversion including the click ID directly to the network, without a browser cookie.
- More robust: independent of ad blockers and cookie lifetimes.
- More accurate: cancellations and returns can be reported afterwards.
- More data efficient: you decide which data is shared.
Data protection still applies
S2S does not replace a legal basis. Check whether your setup requires consent and document the processing (GDPR).
Recommended steps
- Check which networks and partners support S2S.
- Capture the click ID on the visit and store it until the order.
- Set up the postback in your shop or CRM, including cancellation reporting.
- Compare cookie and S2S figures in parallel for a few weeks.

S2S tracking makes your affiliate channel more reliable. The effort is manageable, the gain in data quality is significant. We support you with the switch.
