Payment Refund

To make a refund, run a GET request:

https://unitpay.ru/api?method=refundPayment    
    params[paymentId]=1234512345
    params[secretKey]=x6bh0qbewehfppogkz6lufartkzyv7o0
    params[sum]=100

Mandatory parameters

paymentId	number	Payment ID in the UnitPay system
secretKey	line	Project secret key

Optional parameters

name	type	deescription
sum	number	Refund amount, if a partial refund is required. If the parameter is not passed, the full amount of the payment will be refunded.

You can only make one full or partial refund per payment.

IMPORTANT NOTE: In case of a partial refund of the original amount, there is no protection against duplication for repeated refunds! The only check that is implemented for a partial refund is that you cannot return the same amount within half an hour for the same transaction: an error message will appear.

If you have connected an online cash register in your personal cabinet, you must additionally pass a number of parameters to generate cash receipts.
