​
Prevention Level

Suspicious events are processed according to the set prevention levels.
When the Prevention Level is set to 2 or higher, suspected fraud events are excluded from postbacks. However, you can send them with limitations by completing the Postback settings below.
Data included in postbacks
  • Sends Target events only: Installs (App), Deeplink Opens (App), and Deeplink Pageviews (App).
  • Sends events as unattributed.
  • Sends the identified fraud type.
Eligible channels
  • Postbacks are sent to channels that would have received attribution if not suspected as fraud. These are channels that met all other Airbridge attribution model rules, including touchpoint priority and last-touch attribution (LTA).
  • Postbacks are sent only to channels with the Postback settings below configured.
Postback settings
  • In the postback delivery rule, set [Attribution] to All Events
  • Edit the postback URL as follows. If using the POST method, contact your CSM or reach out through the Airbridge Help Center.
    • Add a postback parameter. Enter the parameter name specified by the channel and select {unattributedTouchpointFraudReason} as the parameter value.
    • Some channels require {unattributedTouchpointClickID} as the Click ID parameter value. Confirm with the channel.
