One-time one-step purchase

Overview

One-time one-step purchase is a payment type which uses only one request to make a one-time transfer of funds from customer to merchant. This is the most basic purchase type in which the customer card or account is immediately debited for the amount of the purchase, for example to pay for an item of goods.

Payment model

To initiate one-step purchase, a request of the sale category should be sent to the platform or the payment form should be opened in the Purchase mode with the sale payment type specified. Once the payment platform receives the request, it creates the sale operation which eventually results in debiting the customer card or account.

A one-step purchase may require the merchant to send the following additional requests:

  • Customer authentication by using the 3‑D Secure technology. In case of working via Gate, for such authentication, the web service is required to accept the corresponding callback and perform the needed actions, while in case of working via Payment Page, all actions needed for authentication are carried out without the web service involved.
  • Customer authentication performed by the payment system on merchant's request. In case of working via Gate, for such authentication, the web service is required to accept the corresponding callback and perform the needed actions, while in case of working via Payment Page, all actions needed for authentication are carried out without the web service involved.
  • Submission of additional payment information for any party involved in the payment processing. In case of working via Gate, for submitting additional information, the web service is required to accept the corresponding callback and send a request with the needed data, while in case of working via Payment Page, all actions needed for that are carried out without the web service involved.

If the payment method supports the capability of confirming that the funds were transferred to the payment recipient, then, after the sale operation has been completed, the payment confirmation operation is initiated in the payment platform. It results in receiving such a confirmation from the provider.

If the payment method supports refunds, after completing a one-time one-step purchase you can return your customers their money if needed. This can be done as a result of a request sent via Gate or as a result of the corresponding action in the tab of the needed purchase in the Dashboard interface. For a refund within a card payment, depending on the refund time and amount and the payment instrument used for the payment, one of the following operations is initiated:

  • reversal if the refund is initiated within the operation day regardless of the purchase amount for a Mastercard card and provided that the total purchase amount is refunded for a card of any other card network;
  • refund if the refund is initiated for a card of any card network after operation day and regardless of the amount and within the operation day provided that a partial purchase amount is refunded for a card of all card networks except Mastercard.

In case of a refund for a purchase processed with the use of an alternative payment method, normally the refund operation is initiated. The reversal operation can be initiated when the purchase is assigned the success status following the confirmation from the payment system or the provider, but the funds cannot be transferred to the payment recipient.
