When a shopper makes a payment using an Alternative Payment Method (APM), the payment is processed in stages, depending on:
The model that you use to integrate with Worldpay
The category of APM that the shopper uses to make the payment
In the direct model, the shopper selects the payment method and provides mandatory data to you before you submit this information to Worldpay. You can also specify your website URLs to which the shoppers must be redirected after they complete the payment
The following figure shows the payment messaging flow for APM payments that are made in the direct model.
