How NMI checks for duplicate transaction¶

No order ID returned¶
It happens when the result code is 3 or 300, and any other un-listed response code (e.g. 0)
the card number did not display in the transaction report¶
It only happens when the submitted card number is more than 19 digit
Why the transaction is in Pending Settlement state and never change to Settle?¶
All of the approved transactions will “always” say Pending Settlement. It’s a difference between US & EU processing banks. In the US, all transactions are “settled” at the end of the day. In the EU though, transactions aren’t really “settled” via a batch. The gateway was originally designed for US merchants, but has expanded into the EU.
