Rejected S2S Webhook Postback

What is the Rejected Report Postback?

A Rejected Postback is a notification sent to external partners when they detect suspicious or fraudulent activities during the user interaction with campaigns or apps. Unlike standard postbacks, which are used to track conversions or user events, rejected postbacks signal that an event has been flagged due to abdonrmal behavior or policy violantions.

Each rejected postback contains a parameter called {rejected_reason_id}, which provides the specific reason for flagging the event.

You can configure your rejected postback by using the parameter we provide for the S2S Webhook postback, along with {rejected_reason_id}.

An example of a Rejected Postback URL looks like this:

https://yourdomain.org/postback?user_id={user_id}&...&payout=0&user_payout=0&rejected_reason_id={rejected_reason_id}

Note: payout and user_payout will be always set to 0 for rejected events.

When a Rejected Report Postback is Triggered

A rejected postback is triggered in cases where an external system identifies behavior that doesn't align with expected norms. Each of these issues is represented by a specific rejected_reason_id in the postback.

How to Set Up a Rejected Report Postback

Rejected Reasons Details

Each postback includes a rejected_reason_id parameter, which indicates why the event was flagged. The following table outlines the available rejected reasons and their severity.

Note: We cannot prescribe specific actions, as enforcement is at your discretion. However, as a reference, here is the policy we apply on our own platforms:

• High severity (first occurrence): Immediate user ban

• Multiple medium severity events within a 7-day period: User ban

• Low severity: Used primarily to inform risk scoring and assess content quality
