Fraud Control

My store is being used to test stolen credit cards. It only blocks high risk transactions. I cannot block medium risk transactions. I've had multiple chargebacks and considering shutting down my store. No help from Shopify.

Very simple and safe rules which allows you to cancel high risk orders, charge payments on not high risk and block customers who left high risk orders.

There is no option to block the whole domain from which the fraudulent transactions / abandoned fake baskets come from. In my case it's @example.com . Multiple different emails from this domain. I cannot possibly block each and every fake email address, I would like to block the whole 'example' domain. Also, there is no option to block specific names/customers.

The app is useful if you take the time to understand and configure the rules correctly. Managing the messaging shown to customers when a checkout is blocked is important, as the default language is too soft for effective deterrence.

One major drawback is the lack of visibility into who is actually being blocked at checkout. All blocked users remain anonymous, so you only see aggregate counts rather than actionable detail. Greater transparency here would significantly improve the product.

Lastly, you can edit what the blocked customer sees by searching the language for "Decision rule block"

To access this app’s functionality, you need to open the “Rules” submenu from the left-hand navigation. Unfortunately, this submenu does not always appear and may require refreshing the browser tab.

Additionally, pinning the app to navigation can cause it to disappear entirely. If this happens, you’ll need to locate the app via search, open the (…) menu in the upper-right corner, and unpin it from navigation. After refreshing your browser and reopening the app from search, Fraud Control should reappear in the left-hand menu under Apps.

At that point, another refresh is often required before the Rules submenu becomes visible.

5 months later, a discovery:

At first glance, it seems like you can only block a single email address per rule, which makes the feature feel pretty limited. It is possible to filter by more specific conditions like IP address, billing address line 1, billing ZIP code, shipping address line 1, and shipping ZIP code, but the interface makes this incredibly hard to discover.

You have to go into “Rules” and add parameters one by one, and each click reveals a RANDOM different field. There’s no visible list of what’s available, so the only way to find them is by repeatedly clicking through options. It’s a very unintuitive setup, but it does allow you to block highly specific details like a billing or shipping address.

A bot is using my store to test stolen credit cards. I contacted Shopify support about it and they said to install this app and it'll help to stop the attacks. Well, this app does nothing to stop the attacks from happening. I'm still getting hundreds of abandoned carts with card details and fraudulent orders are still getting through.

really hard to use

"Rules" does not show, even after refreshing the page many times as one person suggested. This app is broken.

Useful app. make flow creation easier and fraud control analytics helps as well.

I turned on this tool and it didnt block fraudulent orders, now someone opened 53 orders in 3 days and stole nearly thousands of units that will result in thousands of dollars in chargebacks!
