### Configuring Protx VSP Direct Payment Plug-in

The Protx Veri-Secure Payment system (VSP) provides a secure, simple means of authorizing credit and debit card payments and refunds, from your web site.

VSP Direct is designed for merchants who do not wish to redirect the customer away from their site (or who wish to white label the VSP system) and who own a high security SSL certificate from a trusted third party supplier like VeriSign or Thawte.

Please, visit the official Protx website and sign in to create your Protx account and obtain your Merchant ID. After this, you can configure the Protx payment plug-in, test your integration, and go live with Protx VSP Direct Payment.

To configure the Protx payment plug-in:

1. Click the Edit button on the plug-in screen. Fill the form that appears:
   1. Type the Protx Payment Gateway URL into the Server URL field.
   2. Type the URL to send funds capture requests into the Capture URL field.
   3. Type the URL to send refund requests into the Refund URL field.

      Note: Testing URLs can be found in the corresponding Protx documentation. To go live with Protx payment, you should change the testing URLs with actual ones.

   4. Type your Merchant ID received from Protx into the Merchant ID field.
   5. Select at least one credit card type to be accepted by the plug-in from the Available credit card types menu. To select a credit card type to accept with the plug-in, click on a card type name and then click the >> button to move a card type to the Supported Card Types menu. To select several card types in series, hold down SHIFT, and then click the first and last card types of the group. To select several card types that are nonadjacent in the list, hold down CTRL, and click a credit card type.

      Note: To test your integration, you can use test cards enlisted in the Protx integration guidelines.

   6. You can check the Enable pre-authorization box to suspend the amount on the customer's credit card till authorization (the "Preauth" transaction type). After a transaction is authorized, its further processing is performed in accordance with the "funds capture" setting in the Billing Manager Payments Processing.
   7. You can check the Enable AVS/CVV check box to enable additional security features. In this case, you can select the AVS/CVV codes to reject by checking the boxes below. For more details about AVS and CVV, see earlier in this Guide.
   8. You can set the frequency (in hours) for payments status polling, i.e., periodical automated plug-in requesting the payment gateway for transactions processing results. This is the plug-in feature that allows you to monitor payments processing on the payment gateway side. You can enter the nonzero value (number of hours) into the Polling period field, and then the plug-in will establish connection with the payment server and poll payments status with the pre-set frequency.
   9. Key in the Button title. For example, this could be the name of payment system. This title will be displayed directly on the button for online-payment at HSPstore, on the final stage of subscription registration, when a customer selects how to pay for the services ordered.
   10. You can add both the short and the detailed description. Quick description of a payment method will be displayed below the button. The Long description of a payment method will be displayed in a separate section entitled Pay Online.
2. Click the Update button.
