Yesterday I already adjusted the UnionPay refund interface and the callback interface, the UnionPay also returned to my success, but today, after the boss entered the merchant number, we found the transaction amount, the amount of liquidation, that is, the total amount of return is 0, this is what is going on, a lot of 1 cents is said to not return, but there is a 1.17.And a 24 yuan order, shouldn’t???
Are there any friends who have experienced or understood that can solve my doubts?
The refund is made, but the information sent is wrong account adjustment. What is this?
The UnionPay says that SMS is not part of their management. It is a problem on the bank side.
