| 29 | 12 | chin-yeh | h3. Why the transaction is in Pending Settlement state and never change to Settle? |
| 30 | 11 | chin-yeh | |
| 31 | 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. |
