I'm using CIM with php. I'm trying to refund/void transactions.
Is there some clear documentation somewhere about voiding and refunding transactions with CIM?
My understanding is that a transaction can't be refunded until it is "settled". I assume this happens at some indeterminate period of time in the future, and so there was a sentence in some documentation somewhere saying that if a refund is necessary I should simply try to void the transaction and if that fails assume it is settled, and so try a refund. Is this correct?
Is there any expiry date for refund a transaction?
