Fraud Prevention Tools

Fraud prevention tools allow you to automatically void suspicious non-device payments taken from Virtual Terminal and the ecommerce API. They don’t block payments taken from your device. By default, all Hazlnut orders require the Card Verification Value (CVV) and a matching, valid expiration date.

Please let us know if you would like to prevent fraudulent transactions by checking the billing addresses your customers provide with the Clover Address Verification System (AVS).

Clover's AVS has 2 options, both of which we support on Hazlnut:

• Postal Code
• Street Address

How to turn on (Clover):

1. Click on Account & Setup on the bottom left 
2. Under the 'Transaction' group, click on Fraud Tools
3. Click to 'Show Rules' for the Address Verification System (AVS) group
4. Here, there are 6 options that perform different functions. 
5. Make your selection, and click 'Save'. 
6. Please contact support@hazlnut.com with the name of your business, location short name (nickname) and the AVS tool(s) you have turned on.
