The app basically working with Shopify Webhooks and running any time when creating the order in your store.
The app automatically analyzing the order information from Shopify Order Risk API and doing actions which you set on Settings section of the app Whenever you receive a new order, we check it based on Shopify's fraud analysis. If it's a high risk-order, we automatically cancel it, refund/void the payment (if any), restock your inventory, and email a cancellation confirmation to you and the customer (optional).
The app using templates from your Shopify > Settings > Notification section.
"Order canceled" template using when canceling the order,
"Order refund" template using when order refunded.
Our GOAL is - easy to interface and one-click installation. We have all the features what you need in one app. While Shopify automatically flags high-risk orders for you, it doesn't cancel them - you still have to go through your list of orders manually to find and cancel the ones flagged as 'high risk'. Fraud Killer takes care of this for you - automatically.
The App installs itself right away. It just works! If you have any sort of issues, we are always available to help and offer a quality and responsive service!
The App uses Shopify Webhooks. The app does not create or edit any file in your store. After Uninstalling the app, Webhooks turning off.
Good question! Remove Fraud Killer from your app list on Shopify any time before the 7 days are up to avoid starting a monthly subscription.
