Подивится українськоюThe /Reverse request is used to cancel a payment for an order. This functionality is available within a limited period (specified by the bank) after a payment has been executed. The reversal transaction may be performed only once for a payment. If a reversal request results in an error, the next try will fail. Reversals are available to a merchant only if the merchant has an agreement with its bank to perform reversals. To perform the reversal request, a user must have the relevant permissions.
