Making a Payment

The following outlines the how you can make a payment through the WorldPay Payment Service and how we deal with the transaction.

How does the WorldPay Payment Service work?

1. A shopper visits an e-commerce website and selects the products/services that they would like to buy.
2. The shopper then proceeds to the merchant's checkout with their shopping basket. This generates a summary description of the purchase that is sent to WorldPay for payment processing. This submission is often referred to as the "purchase token".
3. The shopper is redirected to WorldPay's secure server where they are presented with a series of payment pages, enabling them to choose their payment method and enter their payment details.
4. WorldPay records the shopper's payment details against the details submitted in the purchase token, to produce a transaction.
5. WorldPay forwards the transaction details to the card issuer for authentication. The issuer returns an authorised or declined response to WorldPay and a payment response page is then displayed to the shopper.
6. If the transaction was successful, WorldPay will also send the shopper a confirmation email, confirming the transaction details.
