Media buyer tool 3 · Postback URL Tester for MGID

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

The affiliate's tracker or network calls MGID's postback URL when a conversion happens, passing the MGID click ID as c. Below: MGID's postback format and macros as MGID's own docs give them, the ways a MGID 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.

MGID's postback format

https://a.mgid.com/postback/123456?c={click_id}&e=purchase&r={revenue}

MGID's click-ID macro: {click_id}. Source: Postback Tracking Method, Conversion Tracking: Setup Checklist, AdsBridge affiliate tracker integration via MGID Ads (read on November 9, 2026). Networks rename macros and some show them only inside your account; if your dashboard differs, it wins.

MGID macros

Macro	Meaning
{click_id}	In MGID's postback: stands for your tracker's macro holding the MGID click ID (change it to the real one)
{revenue}	In MGID's postback: stands for your tracker's payout macro

Parameter names on the receiving side

c: the click ID
e: event/goal name (purchase in the example)
r: revenue
123456 (path): client ID in the URL path

How a MGID postback usually breaks

{click_id} left literal
MGID says {click_id} must be changed to the real one when the postback is set up manually, not with a template.
Fix: Replace {click_id} with your tracker's click ID token.
{revenue} left literal
The same rule applies to {revenue}.
Fix: Replace {revenue} with the payout token or drop r.
One endpoint for several goals
A separate endpoint (link) is required for each conversion goal.
Fix: Generate a postback per goal and set e accordingly.
Click ID parameter not set in Tracking Tags
The checklist step is to obtain a GET parameter for {click_id} in Tracking Tags.
Fix: Add the parameter before running.

Test your MGID postback

Pre-filled with an example: MGID's postback exactly as its help page prints it (123456 is the sample client ID). Replace {click_id} and {revenue} with your tracker's tokens. 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.
