Introduction

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 delivered through webhooks over HTTPS, with Azure Event Grid 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.
