This topic describes how to create an event in the decision engine.
What is an event?
An event is created to define a business scenario that requires risk control. For example, you can create an event for risk control in account registration, marketing, or loan application.
You can create events to define various scenarios and configure a set of risk control policies for each event. Each event has a code. After you pass the code of an event to the decision engine, the decision engine routes a request to the policy set of the event for computing and returns the computing result.
Log on to the Fraud Detection console.
In the left-side navigation pane, choose Decision Engine > Event Management.
On the Event Management page, click Create Event. Set the parameters based on the following instructions:
Event Name: Enter an event name. We recommend that you set an event name that can reflect the scenario. You cannot modify the name of an event after the event is created.
