How long does an S2S postback setup take?

Per offer per network: 3–5 working days from access to live, including QA. Multi-network setups are typically 2–3 weeks total.

Do I need S2S if I am already using Meta CAPI or Google Enhanced Conversions?

Yes — those serve paid-platform optimization. S2S serves affiliate payout truth. Different jobs, different endpoints, both needed.

Can S2S coexist with my existing pixel?

Yes, and that is the recommended migration: run both in parallel for 7–14 days with the network deduplicating on transaction ID, then turn the pixel off as the payout source.

S2S Postback Setup for Advertisers

Server-to-server postback configuration is the single highest-leverage tracking change an advertiser can make. I do it for you, end to end, with QA logs and a written spec your team owns.

Why S2S is non-negotiable now

iOS Safari Intelligent Tracking Prevention, ad blockers, and incognito browsing mean pixel-based attribution drops 20–40% of real conversions for most advertisers. Server-to-server postbacks bypass the browser entirely — fired from your CRM or backend directly to the network when the order reaches a terminal state.

S2S is also the only attribution method that holds up in a partner dispute: you have a timestamped server log of the exact request you sent, with the click ID and payout value, and the network has a matching inbound log. No browser, no cookie, no ambiguity.

What a done-for-you S2S setup includes

Click ID capture verified at every step (landing → checkout → CRM).
Outbound postback handler wired to the network with all required macros.
Event mapping so postbacks fire on terminal status (not pending).
Dedupe rules to prevent duplicate fires from CRM rollbacks or async retries.
Currency and payout validation per offer.
Parallel-run QA against any existing pixel for 7–14 days.
Written tracking spec for partner onboarding.

Stacks I have configured S2S on

Everflow, HasOffers (TUNE), Trackier, Konnektive, Sticky.io, Shopify with custom backend, and a few bespoke advertiser CRMs. The macros and field names change; the configuration discipline does not.
