# Протокол C2B. Возврат ранее принятых QR-платежей (C2B refund)
Возврат по операции QR-платежа (C2B refund) производится по номеру мобильного телефона, с которого выполнялась оплата, и в тот же банк, с которого был первоначальный QR-платеж.
Для протокола С2В refund используется метод [**RefundRequest**.](http://www.moneta.ru/doc/MONETA.MerchantAPI.v2.ru.pdf)
В этом запросе, кроме прочих, требуется передать параметры **transactionId** (операция QR-платежа, по которой выполняется возврат) и **SECUREDFIELD:unsBo\_79=0.**
