Fraud Guard Feature
Order Automator can take actions on orders if they're high risk or medium risk, according to the Shopify fraud analysis.
This feature is included in the Free plan.
For some stats and tips for dealing with fraud orders, see this guide: How to Deal with Fraudulent Orders and Minimize Chargebacks on Shopify
Notifications
Get notified on high or medium risk orders. Useful so your staff can immediately analyze high risk orders and decide whether to cancel them or not.
Auto cancel orders
You can have Order Automator automatically cancel high or medium risk orders.
Note: Sometimes Shopify rejects the request to cancel the order. If they do, you'll get notified at the email you set in Notifications for this feature, or if that's not enabled it will go to your shop email.
Prevent fulfillment
It's a good idea to prevent fulfillment of high risk orders until after you've analyzed them. Enabling this option cancels any fulfillment rules you have enabled by Order Automator, for this order.
