-Please note that STCpay refunds can be done from the STC Pay wallet directly. 

-Important note for partial refunds on STCpay transactions:

To initiate a partial refund for STCpay transaction,  you need to generate a new request for the refund to be able to perform such an action(  and not on the original transaction).
In other meanning, it is not possible to refund part of the transaction with the same reference number as it will be fully reversed to the cardholder. 

Refund can be initiated for either an authorized sale transaction or captured transaction
