Acquirer specific parameters

American Express uses AVS check, see the description on AVS below.

Barclays supports the AVS check, but an automatic decline is not possible through Nets.

To use the AVS check through Barclays, the response is returned to the shop, through both "accepturl" and "callbackurl", has an additional parameter called "avsstatus" that has 6 digit value. This value contains the result of the AVS check, so the shop can choose to decline a payment.

To read this value, use the following table:

If the parameter returned is as the following example:

This means:

Se how to setup AVS in the following description of AVS.

For Giropay to work in FlexWin, the following parameters are mandatory beside the essential parameters:

In some cases, iDeal may respond with an "open" status for new payments, which indicates that the actual outcome has not yet been determined. In these cases, the payment will have the status "postponed" (with status code 26) in the DIBS Administration interface, and DIBS will continuously repoll iDeal to get an update with the status.

If the shop uses callback (automatic server-to-server call) to receive responses from transactions, the initial callback will indicate status 26. To be able to update the system according to the actual outcome of the payment, a notification url may be submitted. When we receive an update for the payment, an additional callback will be sent to this URL with the updated status:

MobilePay online supports sending the customer's mobile number in a parameter called cardholder_mobile:

In some cases, P24 may respond with an "open" status for new payments, which indicates that the actual outcome has not yet been determined. In these cases, the payment will have the status "postponed" (with status code 26) in the Nets Administration interface, and Nets will continuously repoll P24 to get an update with the status.

If the shop uses callback (automatic server-to-server call) to receive responses from transactions, the initial callback will indicate status 26. To be able to update the system according to the actual outcome of the payment, a notification url may be submitted. When we receive an update for the payment, an additional callback will be sent to this URL with the updated status.

P24 requires the following input parameter to be sent to the FlexWin:

Pohjola restricts the maximum length of the orderid parameter to 35 characters.

Tapiola requires the use of the lang parameter.

Available country codes: FR, EN, ES, NL, DE, IT. Can be specified in upper or lower case.

When using Wirecard as your acquirer, an extra parameter is required. Add the following parameter (if not allready included) to the call to Nets.

<input type="hidden" name="cardholder_name" value="insert_cardholder_name_here" />

If this parameter is not sent, the payments may be declined by Wirecard.

Wirecard uses AVS check, see the description on AVS below.

The Address Verification System (AVS) is an advanced level of credit card security that is built in to the specific credit card acquirer to counter identity theft. When a customer makes an online purchase with a credit card their address is required. The address and zip code of the billing address they enter are compared to the address held on file by the card issuing bank. If the address does not match, the transaction can be declined. AVS is an on-demand service so depending on the acquirer you need to at least contact Nets to activate this feature and do some alterations in Nets admin. There is different ways of integrating the AVS check in your payment gateway service, the possibilities will be mentioned below.
 

The following list of acquirers support AVS.

To set up the AVS you have to contact Nets support department. The functionality of your AVS has to be described with the following list.

In order to get this to work on your payment window, you need to make a change in your Nets administration (se the guide in the following section).

The only modification you have to make (if you haven't changed the standard styling) in order to activate AVS from your side, is to go to the Cardholder Info menu in the Nets administration.

In this menu "Address (1)" is used for the address check and "Zipcode" is used for the zip check, see the following example (if you want other cardholder information to be used by Nets you have to check the field, otherwise Nets will see the information as your own parameters).

Configuration	Flexwin apperance

Now you are ready to do Address Verification.

If you want a more custom AVS proceed to step 2.

If  you don't want the customer to fill out the information in the payment process, you can parse the "Cardholder address" and the "Cardholder zipcode" by sending the following parameters along with the FlexWin call.

<input type="hidden" name="cardholder_address1" value="cardholder_address" />
<input type="hidden" name="cardholder_zipcode" value="cardholder_zipcode" />

This way the cardholder address and zipcode will be prefilled in the payment window.

All the other cardholder information can be parsed the same way by adding parameters. See which parameter correspond to which field in the table below.

A full example looks like the following.

<input type="hidden" name="cardholder_address1" value="cardholder_name" />
<input type="hidden" name="cardholder_zipcode" value="cardholder_address1" />
<input type="hidden" name="cardholder_zipcode" value="cardholder_address2" />
<input type="hidden" name="cardholder_zipcode" value="cardholder_zipcode" />
<input type="hidden" name="cardholder_zipcode" value="cardholder_city" />
<input type="hidden" name="cardholder_zipcode" value="cardholder_country" />
<input type="hidden" name="cardholder_zipcode" value="cardholder_phone" />
<input type="hidden" name="cardholder_zipcode" value="cardholder_mobile" />
<input type="hidden" name="cardholder_zipcode" value="cardholder_fax" />
<input type="hidden" name="cardholder_zipcode" value="cardholder_email" />

To archive this, the address and/or zip have to be parsed to FlexWin (please complete Step 1 and Step 2 before proceeding with this guide).

The only way to do a secret AVS check is to remove the input fields in FlexWin by changing the decorator files. This is done by adding the following (or a similar) javascript function in your decorator.js file. If more of the cardholder information should be parsed to DIBS, but without showing them in FlexWin, the array "contentToHide" can be extended with the parameter names.

function hideContent(){
  var contentToHide = ["cardholder_address1","cardholder_zipcode"]

  for(var i=0;i<contentToHide.length;i++){
    document.getElementById("wwgrp_auth_"+contentToHide[i]).style.display = "none";
  }
}

This function hides the cardholder address and zip from FlexWin when activated. Addtional changes in the FlexWin decorators have to be made in the decorator.xml file. In the head of the xml file the following line has to be added.

<head>
...
<script src="/decorator.js" type="text/javascript"></script>
...
</head>

The body tag, or a similare tag, has to be modified as follows corresponding to the javascript function.

<body onload="hideContent()">
</body>

Remember that if you uploade decorator files to FlexWin, you have to follow the Styling documentation.
