What it is
A callback reporting a conversion
A server-to-server request from your system to the tracker at the moment of a target action. Without it, we see clicks but not outcomes, and there is nothing to optimize against.
Before launch
What gets set up
- The event on the product side: registration, verification, deposit
- The address the tracker expects the call on, and the request signature
- A first-week check: the event arrived and was not counted twice
This cannot be rebuilt after the fact: data that did not exist at the moment of the impression cannot be recovered later.What the report looks like.
In practice
Where this shows up
Pages where Postback is not explained but used — in a channel’s mechanics, in a launch breakdown or in a report.
