Pay As Order (Recurring Payments)

How to integrate Pay As Order (information for legacy integrations).

Best practice: We strongly recommend usingTokenisationto manage your recurring payments, because Pay As Order will eventually be phased out.

Activating the service

To activate recurring payments, contact your Relationship Manager.

The process

There are two different XML requests involved:

  • The first request - a standard payment request
  • All subsequent requests - referencing the first request

Follow these steps:

  1. Activate the service and note your assigned merchant code. This additional merchant code is the one you'll use to send subsequent requests.
  2. For the initial payment, create aDirect payment requestorHosted payment requestas normal, using your original merchant code.
  3. Once this initial request has been successfully processed, create a subsequent request using the additional merchant code assigned in step 1.

Create the subsequent request

For all subsequent payment requests you must supply:

  • The <description>
  • The <amount> details of the subsequent request (which can be different from the initial request)
  • The <orderContent>
  • The <payAsOrder> element, specifying the <orderCode> and the <merchantCode> from the original request
  • The <amount> details of the initial request (as child elements of <payAsOrder>)
<?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE paymentService PUBLIC "-//Worldpay//DTD Worldpay PaymentService v1//EN" 
 <paymentService version="1.4" merchantCode="YOUR_MERCHANT_CODE_2"> <!--Enter the additional merchant code you've been assigned-->
     <order orderCode="YOUR_NEW_ORDER_CODE"> <!--Use a unique order code to differentiate-->
       <description>YOUR DESCRIPTION</description> <!--Enter a description useful to you-->
       <amount currencyCode="GBP" exponent="2" value="1399"/> <!--The amount, etc. of this subsequent request-->
       <payAsOrder orderCode="YOUR_ORDER_CODE" merchantCode="YOUR_MERCHANT_CODE"> <!--The order and merchant code from the first request-->
         <amount value="5000" currencyCode="EUR" exponent="2"/> <!--The amount, etc. from the first request-->

Note: You can also supply the cvc in your subsequent requests. To do this, include it as an attribute of the <payAsOrder> element: cvc="123". It will then be returned in the response message from us, as shown below.
