Affected use cases

This chapter applies to the following use cases:
  • Immediate payment with card detail entry
  • Payment in installments
  • Card registration (with or without payment, with or without creating a recurring payment)
  • Payment by token

Payment process

The procedure below applies to CB,VISA, MASTERCARD, AMEX payments.

  1. The merchant website redirects the buyer to the payment gateway by transmitting the payment details (amount, currency etc.).
  2. The payment gateway displays the card detail entry page.

    The buyer selects their payment method and enters the number and expiration date of their card.

    If the card has a security (CVV) code, it must be specified.

  3. The payment gateway proceeds to 3D Secure authentication.
  4. The payment gateway sends an authorization request to the acquirer (the merchant’s bank).
  5. The payment gateway notifies the merchant website about the payment result.
  6. In case of success, the payment gateway displays the summary page with the transaction details.

    If the payment is refused, the payment gateway invites the buyer to try to make another payment.

Creation of the payment form

Response analysis

The 3D Secure authentication result is transmitted in the end of payment notification (IPN) and when the buyer’s browser is redirected to the merchant website.
