Payment Refund

To make a refund, run a GET request:

https://unitpay.ru/api?method=refundPayment&params[paymentId]=1234512345&params[secretKey]=x6bh0qbewehfppogkz6lufartkzyv7o0&params[sum]=100.00

	Value	Description
paymentId	number	Payment ID in the UnitPay system
secretKey	line	Project secret key
sum	number	The refund amount, if the payment system does not support a full refund (Optional parameter). If the parameter is not transmitted, a full refund will be made

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.

You can run the query in test mode. Learn more
