Media buyer tool 3 · Postback URL Tester for ExoClick

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

The affiliate's tracker or platform sends an HTTP GET to ExoClick's tag.php with the stored {conversions_tracking} string (tag) and the goal ID when a conversion happens. Below: ExoClick's postback format and macros as ExoClick's own docs give them, the ways a ExoClick 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.

ExoClick's postback format

ExoClick's click-ID macro: {aff_click_id}. Source: Conversion Tracking (ExoClick docs), ExoClick and TUNE tracking, ExoClick and RedTrack tracking (read on November 9, 2026). Networks rename macros and some show them only inside your account; if your dashboard differs, it wins.

How a ExoClick postback usually breaks

Campaign URL missing {conversions_tracking}
ExoClick ties a conversion to a click only through the ID that {conversions_tracking} fills, so without it there is nothing to return in tag=.
Fix: Add {conversions_tracking} to the campaign/variation URL on a parameter your tracker stores.
Click ID truncated
The ID is at least 150 and at most 700 characters, so a tracker field with a shorter limit cuts it and ExoClick returns ERROR: Tag is invalid!.
Fix: Make sure the tracker parameter stores and returns the full string.
Duplicate or late postback
ExoClick answers ERROR: This conversion has already been notified and saved. for repeats and ERROR: Conversion window is not respected. for late calls.
Fix: Fire once per conversion and within the goal's conversion window.
Dynamic-value goal without value
Goals with a dynamic conversion value need &value=; the affiliate must confirm which token carries the payout.
Fix: Append &value= with your tracker's payout token.

Test your ExoClick postback

Pre-filled with an example: ExoClick's postback with TUNE's {aff_click_id} and {payout} (ExoClick's example) in place of XXXXXXXXX. Replace GOAL_ID with your goal's ID. 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.
