h3. 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.
