APM payment categories and payment messaging flows

When a shopper makes a payment, the Worldpay Payment service sends the payment request to the Payment Service Provider (PSP) for authorisation. The PSP receives the payment request, validates the data, and then initiates the necessary actions to proceed with the payment. The payment process varies based on the Alternative Payment Method (APM) used by the shopper, and the integration model that you use to connect to the Worldpay Payment service.
