Setting-up Payment Notifications (Callbacks)

You use the Merchant Interface to set-up Payment Notifications.

To start or stop Payment Notifications:

1.       Log in to the Merchant Interface using your username and password.

2.       Select the Installations option from the left-hand Menu.
The Installations Page displays with a list your installations.

3.       Select the Spanner button in an Integration Setup column, for the required installation.

4.       Select the check boxes next to the Payment Response enabled? and Enable Recurring Payment Response fields to turn these features ON or OFF.

There are Test and Production columns for each listed installation. If you are setting-up for the first time, select the Test column. This will enable you to develop and test every feature of your Web site Pages before moving the settings to a production environment.

You also need to consider the following:

• Payment Notifications for Recurring Payments (FuturePay) are set to OFF by default

• To ensure that the dynamic payment response feature always sends you a Payment Message, we recommend that you change the payment response URL to include a -ppe modifier and empty property, for example:

<wpdisplay item=MC_callback-ppe empty="http://www.myserver.com/callback.cgi">

This sends the payment message to the default URL defined in the empty property, unless we receive a payment response URL from the purchase token.

• Your Payment Notifications script needs to be able to process the additional cancellation information generated by FuturePay. See Examples of Payment Notifications Data for details.
  
  Your script must identify each transaction as either a FuturePay transaction or a non-FuturePay transaction, and process the data according to your requirements.

• If you are already using Payment Notifications for non-FuturePay payments, don't automatically assume that your Payment Notifications script will work correctly for FuturePay.
  For example, if you use Payment Notifications to generate your own version of our Payment Confirmation Page, you need to check that the page is suitable for a shopper paying by instalments.
  
  Our Recurring Payments service generates data for a cancellation. Tthere is no equivalent to this for non-FuturePay transactions. Your Payment Notifications script needs to be updated accordingly.

See the Payment Response Guide for more details.
