How it works
How a payment reaches you
From the customer's tap to your balance, every step is traceable.
1
Create
Your server calls the API to create a pay-in and gets back a QR code or a checkout link.
2
Customer pays
The customer scans the PromptPay QR or transfers to the assigned account from any banking app.
3
Auto-match
We read the bank statement and match it to the pending payment, or verify the slip the customer uploaded.
4
Notify & credit
A webhook tells your system instantly and the amount lands in your balance, ready to withdraw.
