Does Payeezy Gateway automatically perform a partial authorization reversal when a transaction is settled for less than the original authorization amount?
Yes. Payeezy Gateway will automatically perform a partial authorization reversal any time that the settlement amount is less than the authorization amount.
Example: If a transaction is pre-authorized for $100 but later settled for $50, a partial reversal of $50 will be sent to the card association to reverse the $50 unused in the authorization.
