One-step payment

PCI DSS
The Payment Card Industry Data Security Standard (PCI DSS) is an information security standard used to handle credit cards from major card brands. All companies that process credit card data must be compliant with PCI DSS. This requirement is also applicable to eCommerce merchants who outsource all payment processing to PCI DSS validated third parties, and who have a website that doesn’t directly receive cardholder data but can impact the security of the payment.
Recurrent payments
Recurrent payments occur on a fixed schedule for a pre-agreed amount. For example, monthly utility bills. Unlike installment payments, recurring payments don’t have a fixed duration.
Session
A session represents the customer's checkout session as they pay through the payment page on the Payment Gateway side. Each session is associated with a specific amount and is initiated in the Redirect Integration scenario when the customer opens the payment page. The session ends upon successful payment or automatically expires with a configurable timeout.
Stored Payment Method
A unique token generated by the Payment Gateway that links the customer's card number (PAN) to their ID in the store system (for example, to customer's login). The Stored Payment Method can be used for future purchases so that the cardholder will not have to enter the card data next time. Read more here.
Two-step payment
