Customize postbacks for ad networks with advanced configuration methods.

Suggest Edits

Overview

After enabling basic configurations for your ad network postbacks, you may want to make more advanced edits to the configuration depending on your specific use case and what types of data you want to filter for your postback. In most cases, the default postback URL generated from your selections is sufficient to provide postback notification to interested parties. But sometimes you may need/want to edit or remove a parameter from the postback URL(s) or append a macro expression/variable to include additional information.
