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

The affiliate's tracker calls PopAds' cpixel.php postback URL with the impression ID PopAds supplied. Below: PopAds's postback format and macros as published (PopAds publishes no public postback docs; the format and tokens come from FunnelFlux's and wecantrack's PopAds guides.), the ways a PopAds 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.

PopAds's postback format

https://serve.popads.net/cpixel.php?s2s=1&aid=REPLACE_ME&id={external}&value={payout}

Where this comes from: PopAds publishes no public postback docs; the format and tokens come from FunnelFlux's and wecantrack's PopAds guides.

PopAds's click-ID macro: [IMPRESSIONID]. Source: Tracking setup with PopAds (FunnelFlux; PopAds' own docs not found publicly), PopAds Integration Guide (WeCanTrack) (read on November 9, 2026). Networks rename macros and some show them only inside your account; if your dashboard differs, it wins.

How a PopAds postback usually breaks

aid left as REPLACE_ME
The postback needs your aid, which you copy from PopAds' Pixels and Postbacks page under Conversions.
Fix: Copy the aid from your PopAds campaign.
Impression ID not passed
PopAds identifies the click by [IMPRESSIONID]; if not appended to the tracking link, id is empty.
Fix: Append [IMPRESSIONID] to the click URL, e.g. paclid=[IMPRESSIONID].
Square-bracket tokens
PopAds tokens use square brackets, not curly braces; trackers use curly braces for their own.
Fix: Keep PopAds tokens in the click URL and tracker tokens in the postback.

Test your PopAds postback

Pre-filled with an example: PopAds' postback with a sample account value (aid=123456) and FunnelFlux's tokens. Copy aid from your own PopAds account. Paste your own URL over it; the check runs in this page and fires nothing.

Not PopAds's own macros: {external} (FunnelFlux (tracker)); {payout} (FunnelFlux (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.
