Fraud Prevention in FoxyCart
Foxy's Internal Abuse Prevention
In addition to the options below, we have some systems in place to block more “obvious” fraud. We always recommend relying on your gateway's anti-fraud functionality, but you can rest easy knowing we'll prevent some of the more egregious abuse, before it even reaches your gateway.
minFraud in Foxy
Though we strongly recommend setting up any and all available anti-fraud prevention tools at the gateway level (and most gateways do have fraud controls available, though sometimes at an additional cost), FoxyCart does have integration with MaxMind's minFraud service. Click that link to get a feel for what minFraud is, or just understand that it looks at all the available data from the customer and transaction and provides a riskScore.
What to do with it?
You can enable minFraud in the “payment” page of your FoxyCart admin. Simply set it to any number greater than 0 to enable it. Any transaction with a riskScore higher than the number you enter will be declined.
Though every store and customer base will have different riskScore averages, MaxMind's general recommendation is to definitely reject anything with a riskScore of 60 or higher, and to screen anything with a riskScore between 4-59. FoxyCart defaults to minFraud off, so our recommendation is:
- Set it to 60 to start with.
- Monitor your normal scores (you can see the score on completed transactions) and see what's in a “normal” range.
- Adjust the score down to what's a comfortable upper-normal. For many of our users, that's as low as 4.
If you're already experiencing fraudulent orders, start at 15 or lower instead of 60, as above.
As a potential point of reference, MaxMind shares the following approximate distribution of riskScores across minFraud customers:
|riskScore range||Percent of orders in range|
|0.10 - 4.99||90%|
|5.00 - 9.99||5%|
|10.00 - 29.99||3%|
|30.00 - 99.99||2%|
Make the error message helpful
You can change the language for the error message displayed to the blocked customer in your store's “language” page, under “minfraud”. For example, you could include a phone number at which they would be able to further verify their identities.
Where is the score shown?
On any transaction that has a risk score of greater than 0, an entry for “Minfraud Score” will be shown within the transaction report within the administration.
There's no magic bullet to eliminate all fraud while allowing through all legitimate orders, but with your gateway's fraud filters and FoxyCart's minFraud integration you can get as close as possible.
Google's reCAPTCHA on the Foxy Checkout
Foxy's reCAPTCHA integration can be useful to preventing bots from aggressively scripting and pushing through transactions in an automated way. Note that reCAPTCHA is specifically to ensure that a human must be behind the request, but it has no opinion on whether that human is an honest person or a fraudster.
Foxy defaults to reCAPTCHA being
Enabled, Automatically as Needed, and is our recommended setting, but has 3 different options:
- Disabled: turns off reCAPTCHA for your store
- Enabled, Always: As it sounds, this will include reCAPTCHA on every checkout.
- Enabled, Automatically as Needed: This will require reCAPTCHA for checkouts loaded by IP addresses that have triggered multiple errors in a preceding window of time. We attempt to set this so it would very rarely be shown to a legitimate customer, but would effectively make bot-based bulk fraud impossible. We don't publicize the exact thresholds, and may change them as needed.
Note that reCAPTCHA isn't required for API-based or UOE-based transactions.
Extra Setup if you're using a Custom Subdomain
If you're using a custom subdomain, you'll need to do a few extra steps to get your own reCAPTCHA keys.
- Go to the Google reCAPTCHA admin area. (You'll need to login with your Google Account if you aren't already.)
- Enter a label that'll make it clear what these keys are for. Something like “My Example Store on FoxyCart”, perhaps. This is just for your own use.
- Select the reCAPTCHA V2 option.
- Enter the domain that your FoxyCart account's checkout is using. For example, if your domain was
secure.example.tld, you'd enter
example.tld. Check the checkbox(es) to agree to Google's terms, and submit.
- It should be successful, and take you to a page with your Site Key and Secret Key.
- Copy those two keys into the “payment” page in your FoxyCart admin. (Make sure to put the Site Key in the right input field. Put the “Secret key” into the Foxy admin input for “secret key”.
- Save the payment settings in the FoxyCart admin.
- Do some test transactions, if you'd like. (You can set the reCAPTCHA setting in your Foxy settings to “Enabled, Always”, then load up your checkout. You should see the reCAPTCHA display on the checkout. Set it back to “Enabled, Automatically…” once you're done, if you'd prefer.)
FraudLabs Pro has built an anti-fraud integration for Foxy. There's a little setup involved, but there are step-by-step instructions here:
