On-demand COF purchase

Overview

On-demand COF purchase is a payment type which uses a single initial request to make one 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 purchases 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.

The payment workflow

A COF purchase becomes available only after you perform an initial purchase in which you specify the COF purchase type and instruct the payment platform to save customer's purchase credentials. To do so, you need to include in the initial request the recurring object that contains the register and type parameters.

You initiate COF purchase by sending a recurring request to the payment platform. Once the payment platform receives the request, it creates a recurring operation which eventually results in debiting customer card or account without payment instrument validation.

In rare instances, a COF purchase may require you to send another request to submit additional information requested by one of the stakeholders, for example to provide cardholder address which is missing from the initial request. In this case, the payment platform sends to the web service a callback with the names of the missing parameters, suspends the purchase processing, and waits until the web service submits a clarification request with the values for the missing parameters.

If the payment method supports refunds, after completing an on-demand COF purchase you can return your customers their money, if needed. You initiate a refund by sending a refund request to the payment platform. Refund is performed by using one of the following operations:

  • 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.
