Understand the why behind every fraud block
We’ve made it easier to see how fraud decisions are made. Now, when a payment is blocked or flagged, you can view the specific signals our machine learning models used to assess the risk, drawing from your own data, checkout inputs, and our global network.
Make more informed decisions
This transparency helps you evaluate the model’s logic and adjust your setup with custom rules when needed. Whether you're looking to refine your risk settings or provide clarity to operational teams, these insights are now at your fingertips.
Explore the signals
To access the signals, go to any card based payment that was fraud disputable (e.g. a Mastercard payment). You can do so via the Customer Area > Transactions > Payments > Select a payment and click on the Risk score.
