To start using AntiFraud for your X-Cart store, you will need to install the AntiFraud Service Connector add-on. Follow the instructions from Installing Add-ons from X-Cart App Store.

Once the add-on has been installed, proceed to the add-on settings page to configure it.

On the add-on settings page, there are three tabs. You need to check and configure the settings on each of them:

Settings tab

  • AntiFraud module service key : Specify the service key you’ve got in the subsciption confirmation e-mail.

  • Fraud risk factor threshold value : Specify the fraud risk factor threshold value. Orders with a Fraud risk factor greater than the value specified in this field will not be processed automatically. If fraud risk factor is greater than this limit, the order status will be ‘Queued’.

A fraud risk factor value that will be provided by AntiFraud service with reference to a certain order will be a number from 1 to 10 (the greater the number, the higher the probability of fraud). The field Fraud risk factor threshold value allows you to specify, how great a fraud risk factor of an order must be for the order to be considered fraudulent.

For example, if you set the Fraud risk factor threshold value to ‘5’ (which corresponds to 50% risk of fraud), all the orders with the fraud risk factor rates from 6 to 10 will be considered potentially fraudulent. X-Cart will not process such orders automatically: they will be placed with the status ‘Queued’, so you will be able to review them personally at a later time and decide, whether you want to process them or not. If you find a certain order to be fraudulent, you will be able to report the IP address from which the order originated to the AntiFraud service server as a source of fraudulent orders. This will prevent further fraudulent orders coming from this IP.

  • Block order processing if risk score execeeds threshold : If you enable this X-Cart won’t even send an order to a payment gateway for processing if fraud score is bad. In this case the special “AF Error #1: Cannot process this order. Contact administrator” message is displayed for the customers at checkout.

  • Use AVS check result returned from the gateway : If enabled customer’s billing address will be compared on checkout against the information stored on file by a credit card issuer and any suspicious transactions will be blocked if the information provided doesn’t match with the one stored on the credit card. The setting works for X-Payments subscriptions only.

  • AntiFraud safe distance (km) : The distance between a billing address location and an IP address location that you wish to be treated as safe. Any order originating from an IP address located within the AntiFraud safe distance from the address provided by the customer at checkout will be processed as non-fraudulent. For all users outside the safe distance, the risk of fraud will be defined based on the Fraud risk factor threshold value.

  • Order total threshold : The order subtotal amount starting from which an order must be considered ‘large’. AntiFraud service believes large orders to provide a greater risk for store owners, so it uses an additional coefficient to increase the Fraud risk factor of an order if its subtotal exceeds the value provided in this field.

  • Run AntiFraud check on orders with zero order total : This option allows you to specify whether you wish orders whose order total amount has been calculated as ‘0’ (zero) to be screened by AntiFraud service.

  • Force to use the “Auth only” mode if the fraud risk factor exceeds : Define the maximum allowed value of the fraud risk factor. When exceeded, X-Cart will force to perform the transaction in the “Auth only” mode even if the payment system is set up to use a different mode.

  • Address error score : Define any score from 0 to 10 that will be assigned to an order in case the AntiFraud service is not able to process customer’s address.

  • “AntiFraud service key is invalid” notification to orders department : This option allows you to specify whether you wish an email notification to be sent to the store’s Orders department if the value entered into the ‘AntiFraud module subscription key’ field is not a valid subscription key.

  • “AntiFraud service key is expired” notification to orders department : This option allows you to specify whether you wish an email notification to be sent to the store’s Orders department when your AntiFraud add-on subscription key expires.

Submit the settings when you are done.

Payment methods tab

Here you will see a list of payment methods enabled in your store. You need to select the payment methods falling under the AntiFraud check. AntiFraud check will be performed on orders placed using the specified payment methods only.

High risk countries tab

Create a list of countries that should be blocked by AntiFraud service (a kind of "black list"). Customers from these countries will not be able to place orders at your store.

To add a country to the list, choose the country from the drop-down box and click Add.
