3. App ID (APPID)

3.1 What is an App ID?

In the KYT Rule Engine, users can create an App.

An App represents a customized risk configuration, including:

• Risk type thresholds

• Risk Level adjustment rules

• Alert triggering logic

After creating an App, the system will display the corresponding App ID at the top of the page.

3.2 How App ID Works

When calling OPENAPI endpoints:

• If appid is NOT provided → The system uses the default Risk Engine configuration.

• If appid is provided → The Risk Engine dynamically adjusts risk evaluation results → Based on the user-defined Risk Threshold configuration.

This allows clients to implement personalized risk control strategies.
