Media buyer tool 3 · Postback URL Tester for Awin

Test your Awin postback URL before the next conversion goes missing.

Awin calls the publisher's Call-back URL (GET) when a transaction is tracked, replacing !!!macro!!! placeholders with transaction values. Below: Awin's postback format and macros as Awin's own docs give them, the ways a Awin postback usually breaks, and the tester, pre-filled with an example of the postback the platform fires to your tracker. Edit it to match yours and run the check.

Nothing you enter leaves your browser.

Awin's postback format

https://www.yourdomain.com/awin/transaction-handler.php   (the docs' Call-back URL example; macros such as !!!clickRef!!! are appended as GET parameters)

Awin's click-ID macro: !!!clickRef!!!. Source: Transaction Notifications (Awin developer docs) (read on November 9, 2026). Networks rename macros and some show them only inside your account; if your dashboard differs, it wins.

How a Awin postback usually breaks

clickref not set on the tracking link
!!!clickRef!!! returns the publisher-defined click identifier; if the link has no clickref the callback arrives with an empty click ID.
Fix: Add clickref={your click ID macro} to the Awin link (clickref2-6 for extra values).
Wrong placeholder syntax
Awin placeholders use triple exclamation marks (!!!name!!!), unlike the {name} style elsewhere; {clickRef} is not substituted.
Fix: Write !!!clickRef!!! exactly.
JSON macros combined with others
!!!commissionGroups!!! and !!!products!!! must be used alone as the parameter value because they expand to JSON.
Fix: Give each its own parameter and do not concatenate.
Wrong HTTP method
The macros are GET request placeholders, so configuring the callback as POST sends them differently.
Fix: Set the Call-back method to GET.

Test your Awin postback

Pre-filled with an example: Awin's macros in an example tracker postback (track.example.com stands for your tracker). Paste your own URL over it; the check runs in this page and fires nothing.

Your postback URL templateExactly as you gave it to the network, macros and all. If it contains an API key or token, the value is removed before anything is shown.Your offer link with its macros (optional)The link your tracker sends visitors to. It lets the tester check the click ID goes out and comes back in the same field.

Your network's click-ID macroThe macro the network fills with the click ID you sent it. It also tells the tester which syntax the network uses.

My funnel has more than one event (e.g. registration, then deposit)Then the postback needs a status or event-type parameter.A real click ID from your tracker (optional)Used only in the test-fire URL, so a test lands on a click you can find.

Want me to trace one real campaign?

This tool checks the postback URL and offer link you pasted from what you typed. It can't see your ad accounts, tracker, network or live traffic. If the result shows gaps, I'll look at one real campaign for free: I trace it from ad click to payout and back, and within 48 hours I send you a written report on where money or data leaks silently, the fix for each, and the tests that prove it's fixed.

In the review I fire a test conversion end to end on one real campaign and check it lands once, with the right payout, in your tracker and in your traffic source. You get the fix for every place it doesn't.
