Security - IP Whitelisting

Verifying the authenticity of a payout event is critical to preventing fraud. Fusion offers a signature that can be checked to verify authenticity of Postbacks.

Some publishers choose to implement IP whitelisting to ensure the postback is fired from the correct source. You can expect to recieve postbacks from the following IP addresses:

• 34.226.25.42

• 54.198.176.221

• 52.44.16.173

Note: This is subject to change depending on upgrades and updates necessary in maintaining security.
