How to Use

What is a Postback Tester? A postback is an HTTP callback that sends conversion notifications from attribution platforms or affiliate networks to the advertiser's server. The URL usually contains macro placeholders such as click_id, aff_sub and payout. This tool parses callback URLs, identifies macros and previews the expanded result.

How to use 1. Paste a complete attribution callback URL (e.g. an S2S postback URL from a tracking platform). 2. Review the query parameter breakdown; parameters containing macros are highlighted. 3. Edit sample values in the macro section and copy the expanded URL in real time.

Common macros - click_id: unique click identifier - aff_sub series: custom sub-channel parameters - offer_id / aff_id: offer and affiliate IDs - payout / currency: conversion commission and currency
