  3. Enable the Anti fraud add-on (change its status to Active on the right).
  4. Choose Settings from the drop-down list under the button with the "gear" icon.
  5. Enter your Maxmind license key and define the desired parameters in the corresponding fields:
    • Safe distance (km) - allowed distance from customer's IP address to his/her billing address in kilometers (large distance =  higher risk, it affects risk factor);
    • Max order total - if order amount exceeds the defined max value it affects risk factor;
    • Maximum risk factor (1...100) - set a number from 1  to 100 (25 is recommended). If the risk factor exceeds this number then  the order is held for review and it will have Open status even if the transaction is processed by payment gateway or system. Store  administrator will need to decide whether the order is fraudulent or not and then set the order status to Failed or process it manually.
