Besides pixels, every Tracking Link can call your own URL on each conversion. This is how you feed Keitaro, Binom, Voluum, a spreadsheet endpoint or any custom backend.

​
Postback URL

Set the URL in the link’s Destinations section. It is called on every conversion event of that link: new subscribers, transactions and chat dialogs. Use the {{event}} macro to tell them apart on your side.
Macros are filled per event and URL-encoded automatically. Fields that do not apply to the current event resolve to an empty string: for example, {{transaction.amount}} is empty on a subscription event.

​
Macros

​
Click

​
Subscriber

​
Transaction (transaction events only)

​
Campaign

The macro picker under the URL field in Studio inserts any of these with one click, so you do not have to type them.

​
Delivery rules

  • Events are queued the moment a conversion is detected and usually leave within a minute.
  • Your endpoint must be publicly reachable over HTTP or HTTPS. HTTPS certificates are verified.
  • Any HTTP response completes the delivery; the status code and body are stored in the log.
  • If the request cannot complete (timeout, connection refused), it is retried up to 3 times, 10 minutes apart.
  • A stopped link sends no further conversion events. The marketing_stop event is the exception, so trackers can close the campaign.

​
Delivery log

Tracking Links > Logs shows every delivery for all your links: pixels and custom postbacks in one place. Filter by link, event, platform and state, and expand any row to see the exact request and the exact response. The log refreshes automatically every 10 seconds, so you can keep it open while testing: click your link with a test click_id, complete a subscription, and watch the event arrive and get delivered. Access tokens and other credentials are masked in logged requests.
Pixel test events sent from the Test button go directly to the platform’s Test Events tool and do not appear in this log. The log shows real conversion traffic.

​
Troubleshooting

No conversions have happened yet. Clicks alone do not create deliveries; events fire when a fan subscribes, pays or chats. Check the link’s stats for fans first.
Expand the row. The response code and body are the endpoint’s own answer: a 404 means the URL path is wrong, a 401/403 means your tracker expects other credentials, a Meta or TikTok error message names the exact field it rejected.
The visitor arrived without a click_id parameter, and no ad platform ID was captured. Confirm your ads point at the Tracking Link URL with &click_id={your_tracker_macro} filled by the tracker.
