What is Postback and Where Can I Get the Postback URL?

Postback (pingback, 2s2 pixel, postback, pingback) is a mechanism to transfer data from an affiliate program (or from an advertiser) to a tracking system, provided that the user has performed the target action.

The Postback URL can be found in your campaign settings. Please scroll down to the "Conversion Sensors", turn them on, and select the “Postback” option from the drop-down “Goal Type” menu.
