Payment Service Providers (PSPs)

When a shopper makes a payment, the shopper data is sent to the appropriate Payment Service Provider (PSP) for validation and authorisation. Depending on the payment method used, if the shopper data is valid, the PSP either:

Authorises the payment, without prompting the shopper for any further information. The payment pages of the PSP therefore remain invisible to the shopper

Prompts the shopper to do additional tasks to complete the payment. For example, if a shopper makes a payment by bank transfer, the PSP prompts the shopper to choose their online bank and proceed with the payment

After the PSP confirms the outcome of the payment to Worldpay, the Worldpay Payment service returns the result of the transaction to you.

Note: Some PSPs who provide the APMs (for example SOFORT, Bancontact and others) insist that shoppers enable JavaScript and third party cookies on the browser. If these are not enabled, some APMs will not work. We therefore recommend that merchants tell their shoppers to have JavaScript and third party cookies enabled before shoppers select and use an APM.
