Postback setup: the 3 checks that prevent missing CPA conversions

Postback setup: the 3 checks that prevent missing CPA conversions

Voluum, RedTrack, and Binom all need the same handshake: a stable click ID. The tracker creates it, the offer URL carries it, and the CPA network returns it in the conversion postback.

Setup checklist:
• Put the tracker’s click-ID macro into the offer URL parameter required by the network: clickid, subid, or another named field.
• Put the tracker postback URL in the network and replace its placeholder with the network’s click-ID macro.
• Map the correct conversion event and pass payout only if the tracker expects it.

Run one test click and inspect raw URLs and logs on both sides. The ID must match exactly, appear once, and survive URL encoding. If the conversion is missing, check parameter names, macro syntax, and whether the network sent an approved event before changing attribution settings.

Keep a token map for each network and campaign. Once one campaign completes the full round trip, reuse that template and test a rejected or duplicate event when available.

Treat the postback as a chain: click ID in, conversion out, matching record in both systems.
