What is BankID Antifraud?#

BankID Antifraud is a system that monitors each BankID transaction for suspicious activity. When potential fraud is detected, the system distributes alarms to merchants in real-time, helping you protect your users and systems from fraudulent transactions.

The system uses CloudEvents⁠ (opens in a new tab) delivered through webhooks over HTTPS, with Azure Event Grid⁠ (opens in a new tab) as the delivery mechanism.

How it works#

When the BankID antifraud system detects suspicious activity, it generates an alarm event. This event is then delivered to your webhook endpoint in real-time, allowing you to take appropriate action.
