Payment Refund
It is possible to refund particular payments within the Sale. This is equivalent to the Sale Return, but without involving items or partial amounts.
Info
Refunds can be used for cases where the customer changes their mind immediatelly after the payment and Sale Reversal is no longer possible (Payment already sent for settlement to respective network) or if the customer wishes to replace completed payment method with alternative one.
Warning
The execution of payment Refund is bound to a Sale being in the Unconfirmed or Failed Intervene states. If your Sale is in a different state, such as Completed, what you are looking for is a Partial Return - in which case you can decide what payment method the Partial Return applies to. For further details, see the samples in the Return section.
