Postback Tracking: Server-to-Server Conversion Measurement
Postback tracking reports conversion events between servers, typically using a click ID or transaction identifier to match the event to an earlier interaction.

The core idea
It is widely used in affiliate marketing because the publisher often cannot place a browser pixel on the merchant’s confirmation page.
What matters in practice
Correct parameter mapping, secure endpoints, deduplication and test conversions are essential.
Decision rule
Postbacks improve delivery resilience but do not solve an incorrect attribution model.
Tracking principle: Define the business outcome first, then choose the measurement method and software. A sophisticated dashboard cannot repair unclear event definitions or inconsistent campaign naming.
