How orders update
Paying
At checkout the shopper goes to VNPay’s secure payment page and pays by VNPAY-QR in a banking app, domestic ATM card, international card or e-wallet, as your terminal offers them.
Paid
When VNPay confirms the payment, Tringify marks the order paid within seconds.
Failed or left unpaid
If the payment is declined, cancelled or expires, the order stays unpaid and the shopper can choose another way to pay.
Checked every few minutes
VNPay tells this app when a payment completes, and every few minutes Tringify asks VNPay about any payment that's still open, so nothing is missed.
Currency
VNPay takes Vietnamese dong (VND) only. Turn VNPay on in markets that price in VND.
