Media buyer tool 3 · Postback URL Tester for Clickadu

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

The affiliate's tracker calls the Clickadu postback (S2S) link, generated in Clickadu's Tracking section, when a conversion happens. Below: Clickadu's postback format and macros as published (Clickadu's own pages show the postback only in screenshots; the literal URL comes from Voluum's Clickadu guide.), the ways a Clickadu postback usually breaks, and the tester, pre-filled with an example of the postback your tracker fires back to the traffic source. Edit it to match yours and run the check.

Clickadu's postback format

http://sconvtrk.com/conversion/bcfa78da6ca18f569d0ce1295d3de8280176c5a7/?visitor_id={externalid}&aid=236486

Where this comes from: Clickadu's own pages show the postback only in screenshots; the literal URL comes from Voluum's Clickadu guide.

Clickadu's click-ID macro: ${SUBID}. Source: How to integrate Clickadu S2S conversion tracking, How to integrate conversion tracking with Voluum (Clickadu FAQ), Clickadu Template Integration (Voluum docs) (read on November 9, 2026). Networks rename macros and some show them only inside your account; if your dashboard differs, it wins.

Clickadu macros

Macro	Meaning
${SUBID}	Clickadu's token, corresponds to a visitor ID (the click ID); replace with the tracker's visitor ID token in the copied link
{cost}	Cost (Clickadu tracking token per Voluum template page)
{zoneid}	Zone ID (Clickadu tracking token per Voluum template page)

Parameter names on the receiving side

visitor_id: The Clickadu click ID passed back (filled with the tracker's click ID token)
aid: Clickadu account ID; differs per account

How a Clickadu postback usually breaks

Leaving ${SUBID} in the copied postback
The generated link contains Clickadu's own ${SUBID} token; Clickadu's guide says to change it to your tracker's token. If left as is, the tracker receives the literal text and cannot match a click.
Fix: Replace ${SUBID} in the copied link with your tracker's click ID token (e.g. {externalid} in Voluum).
${SUBID} parameter not added to the traffic source
Clickadu's guide says to create an extra parameter holding ${SUBID} and name it; without it the click ID never reaches the tracker, so there is nothing to post back.
Fix: Add a named parameter with value ${SUBID} to the tracker's traffic source and save.
Wrong aid or hash
The postback is account-specific (aid=236486 in the sample is only an example); a link copied from another account or edited by hand will not credit your campaign.
Fix: Copy the postback from Clickadu's Tracking section after selecting your tracker.
Postback toggle not enabled
In Voluum the traffic source postback URL toggle must be enabled before the pasted URL is used.
Fix: Enable the traffic source postback toggle and paste the URL.

Test your Clickadu postback

Pre-filled with an example: The postback from Voluum's Clickadu guide (its sample hash and aid) with Voluum's {externalid}. Copy your own from Clickadu's Tracking tab. Paste your own URL over it; the check runs in this page and fires nothing.

Not Clickadu's own macros: {externalid} (Voluum (tracker)).

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.
