Media buyer tool 3 · Postback URL Tester for ClickFlare

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

The affiliate network calls ClickFlare's /cf/cv postback URL when a conversion happens, returning the click ID it received in the offer link. Below: ClickFlare's postback format and macros as ClickFlare's own docs give them, the ways a ClickFlare postback usually breaks, and the tester, pre-filled with an example of the postback URL your affiliate network calls in. Edit it to match yours and run the check.

Nothing you enter leaves your browser.

ClickFlare's postback format

https://your_clickflare_domain.com/cf/cv?click_id={clickid}&payout={payout_token}&txid={transaction_id}&ct=sale&payout_currency=USD&param1={network_subid}&param2={user_device}

Set by your network, not by ClickFlare: put your network's click-ID macro in the click_id= field. Source: ClickFlare Parameters in Postback URLs, How to Submit an S2S Postback URL to an Affiliate Network in ClickFlare (read on November 9, 2026). Networks rename macros and some show them only inside your account; if your dashboard differs, it wins.

How a ClickFlare postback usually breaks

REPLACE left in click_id
The ClickFlare template ships as click_id=REPLACE&payout=OPTIONAL&txid=OPTIONAL. If REPLACE stays, ClickFlare cannot match the conversion to a click and the conversion is lost.
Fix: Replace REPLACE with the exact click ID token the network uses for the sub parameter you put in the offer URL.
Wrong network click ID token
A wrong click ID token means ClickFlare cannot match conversions to clicks, causing lost or inaccurate data.
Fix: Use the same parameter in the postback that the network uses in the offer link (from its postback settings or your affiliate manager).
OPTIONAL/unused placeholders left in the URL
Remove parameters you don't use (payout, txid) rather than leaving placeholder text in them.
Fix: Delete payout= and txid= if the network does not send those tokens.
No payout means no revenue
Without the payout parameter ClickFlare does not track revenue automatically.
Fix: Map payout to the network's payout token, or set a fixed payout on the offer.
Network only supports pixels
The submit-postback article notes some networks only support pixel tracking, so a server postback may not be possible.
Fix: Confirm postback support with the network before relying on it.

Test your ClickFlare postback

Pre-filled with an example: ClickFlare's postback with an example network's macros (CAKE's) in place of its token slots. Paste your own URL over it; the check runs in this page and fires nothing.

Not ClickFlare's own macros: #s2# (CAKE); #price# (CAKE); #tid# (CAKE).

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.
