Media buyer tool 3 · Postback URL Tester for ClickMagick

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

The affiliate network calls your ClickMagick Postback URL (with your uid) when a sale, action or engagement happens. Below: ClickMagick's postback format and macros as ClickMagick's own docs give them, the ways a ClickMagick 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.

ClickMagick's postback format

https://www.clkmg.com/api/s/post/?uid=[USERID]&s1={TRACKID}&amt=0.00&ref=

Set by your network, not by ClickMagick: put your network's click-ID macro in the s1= field. Source: ClickMagick Knowledge Base: postback URL templates (answer 274), ClickMagick Knowledge Base: webhook tokens (answer 217) (read on November 9, 2026). Networks rename macros and some show them only inside your account; if your dashboard differs, it wins.

ClickMagick macros

Macro	Meaning
{TRACKID}	Placeholder in s1={TRACKID}; replace with the token your affiliate network uses
[USERID]	Your ClickMagick user ID (from the Postback URL Tool)

Parameter names on the receiving side

uid: Your ClickMagick user ID
s1: Tracking ID value returned by the network
amt: Sale amount (Sales postbacks only)
ref: Reference value of the conversion
cmc_tid: URL parameter on your click link that carries the unique value ClickMagick tracks

How a ClickMagick postback usually breaks

Template used as-is
s1={TRACKID} is a placeholder and must be replaced with the actual token the affiliate network uses.
Fix: Copy the URL from the Postback URL Tool or insert the network's token.
Wrong path segment for the event type
/s/ is a sale, /a/ an action, /e/ an engagement. Using /s/ for a no-amount event or the wrong type misclassifies the conversion.
Fix: Change /s/ to /a/ or /e/ for actions and engagements and drop amt.
Tracking value not passed on the click
The link should pass the unique value in the cmc_tid parameter; if the network never receives it, the postback has nothing to return.
Fix: Make sure the click link includes cmc_tid and the network passes it back.
Test click with dynamic tokens
A general warning on the integrations page says dynamic tokens will not work for the test click.
Fix: Test with a real click instead of the test-click tool.

Test your ClickMagick postback

Pre-filled with an example: ClickMagick's postback with a sample user ID (uid=12345) and an example network's macros (CAKE's) in place of {TRACKID}. Paste your own URL over it; the check runs in this page and fires nothing.

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