Set up minFraud fraud screening

How to set it up

1. 1

   Go to the Foxy admin

2. 2

   Go to Settings > Payments

3. 3

   Click on the payment method set you want to protect

4. 4

   Under Fraud protections, click Add fraud protection + and select MaxMind minFraud (or click the existing MaxMind minFraud entry to edit it)

5. 5

   Set the Rejection threshold to a number between 0 and 100

6. 6

   Close the panel to save your changes

The rejection threshold works as follows:

• 0 disables minFraud.

• Any number between 1 and 99 declines transactions with a risk score higher than that number.

• 100 turns minFraud on for logging only — scores are recorded, but all transactions are allowed through.

Choose a threshold

Every store and customer base has different average risk scores, but MaxMind's general recommendation is to reject anything scoring 60 or higher and to screen anything scoring between 4 and 59. Our recommendation:

1. 1

   Start with a threshold of 60.

2. 2

   Monitor the scores on your completed transactions to see what a normal range looks like for your store.

3. 3

   Adjust the threshold down to a comfortable upper end of normal. For many stores, that's as low as 4.

If you're already experiencing fraudulent orders, start at 15 or lower instead.

As a point of reference, MaxMind shares this approximate distribution of risk scores across minFraud customers:

Customize the error message

You can change the error message shown to a blocked customer in your template set's language string overrides. For example, you could include a phone number the customer can call to verify their identity.

1. 1

   Go to the Foxy admin

2. 2

   Go to Settings > Templates and click on the template set you want to modify

3. 3

   In the language string overrides, open the Minfraud category

4. 4

   Edit the minfraud_highrisk_transaction string (there's also a minfraud_api_error string for API errors)

View minFraud scores

Any transaction with a risk score greater than 0 will show its minFraud score in the transaction details in the Foxy admin [VERIFY: exact label in the transaction view — needs a store with a scored transaction].

Notes

• Fraud protections are configured per payment method set. If your store uses multiple payment method sets, add minFraud to each one you want to protect.

• minFraud applies only when the customer enters their card details directly on the Foxy checkout. Exceptions: Adyen Embedded, Amazon Pay, Apple Pay, Klarna, Square, and Stripe.

• We strongly recommend also enabling any anti-fraud tools available at your payment gateway. Most gateways offer fraud controls, though sometimes at an additional cost.

• There's no threshold that blocks all fraud while allowing every legitimate order through. Combining your gateway's fraud filters with minFraud gets you as close as possible.
