On-demand COF purchase

Notice: This article provides a general description of processing on-demand COF purchases in the ecommpay payment platform and covers information about operations utilised to execute a payment of this type and statuses that are assigned to the payment and the operations performed within it.

In addition, use the following materials to gain a fuller understanding of processing COF purchases:

  • COF purchase registration—an article that covers registering COF purchases via Payment Page and describes requests and callbacks that are used in case of card payments.
  • articles of the Payment methods section containing a description of COF purchase registration via Payment Page with the focus on the specific features of the payment method used and information about relevant requests and callbacks.

Overview

On-demand COF purchase is a payment type which uses only one request to make one (recurring) transfer of funds from customer to merchant by using previously stored payment credentials but without validation of the payment instrument (such as card validation code, or CVC).

The on-demand COF purchase are used for purchases that use the same payment instrument for repeatable miscellaneous purchases with variable amount and no specific schedule, for instance to pay for taxi services. On-demand COF purchases are convenient because they do not require customer to enter payment credentials and to validate payment instrument for each purchase.

Payment Page supports registering COF purchases and performing express purchases (OneClick) for some payment methods. OneClick purchases are on-demand COF purchases with each withdrawal of funds initiated by the customer.

Payment model

An on-demand COF purchase by using Payment Page becomes available only after initial purchase in which the merchant specifies the COF purchase type and instruct the payment platform to save customer's purchase credentials. The set of the parameters that are required for the subsequent COF purchases processing may vary depending on the payment method (more: Methods).

The merchant initiates the registered on-demand COF purchase by specifying in the request for opening the payment form the purchase operation mode and additional parameters required for performing COF purchases using a particular payment method (for more information about initiating COF purchases, see Methods). Once the payment form opens, the customer should select the payment instrument for which the COF purchases are registered and confirm payment processing. Authentication is not required. As soon as the customer confirms payment processing, request is sent to the payment platform. Once the payment platform receives the request, it creates the sale operation.

In rare instances, a COF purchase processing may involve clarification of the information, for example, clarification of cardholder address which is missing from the initial request. This procedure does not require the merchant to perform any steps, but it requires customer's actions.

If the payment method used for making the payment supports refunds, after completing this type of purchase the merchant can perform refund and return the customers their money, if needed. Refund processing is initiated using Gate or Dashboard, and one of the following operations is performed:

  • reversal—this operation is used when refund is performed on the same business day as the initial purchase.
  • refund—this operation is used when refund is performed after the business day of the initial purchase is closed.
