A postback is a conversion reported from the advertiser's server to the platform, instead of from a tag in the visitor's browser. It is one of the three ways to connect tracking, next to store plugins and the one-line tag.
Why use a postback
- No browser needed. Ad blockers, closed tabs and blocked scripts don't lose the conversion.
- Conversions that happen later. A sign-up approved the next day, or a sale confirmed by a call centre, can still be reported.
- Trackers. Third-party trackers such as Voluum, RedTrack, Binom and Keitaro report conversions by postback; the Tracker Connect plugin connects them.
How it works
- The platform adds a click ID to the landing page link automatically.
- The advertiser's system stores the click ID with the visitor.
- When the conversion happens, the system calls the postback URL with that click ID, and optionally the value.
- The platform matches it to the click, counts it once and credits the campaign and placement.
Setting it up
- Copy the postback URL from the conversion setup page.
- Make sure the landing page keeps the click ID through every redirect.
- Send a test conversion and check it's matched.
- Watch the conversion health check for the first days.
