About normalUrl

• When accepting payments from BAY, you can choose whether to use normalUrl:

• If choosing not to use normalUrl, you can directly render the codeValue in the API response on the merchant page to display the QR code or payment code, reducing page redirections and improving the payment experience.
• If choosing to use normalUrl, redirect your buyer to the address specified by normalUrl and proceed the payment process as indicated in User experience.

• For WAP and App terminals, normalUrl is returned in the response of the pay (Checkout Payment) API. The buyer is redirected to the address specified by normalUrl and uses the payment code displayed on the page to proceed with the payment within the mobile banking app or on the offline ATM device. After the payment is completed, the middle page automatically redirects to the merchant result page.
• Different terminal types have specific integration features when returning normalUrl.

• WAP: The returned normalUrl is the payment code and payment operation display page. The buyer copies the payment code and proceeds to the bank app or the ATM based on the payment operation or the screenshot to complete the payment.
• App: The returned normalUrl does not trigger the payment method app. It is recommended that you render the URL page directly within the merchant app and provide payment operation steps to guide buyers to complete the payment.
• Web: Not supported on PC.

After payments

• After the buyer completes the payment in the bank app, the banking app will not automatically redirect to the merchant's results page. The buyer needs to manually navigate to the transaction initiation app (the merchant app or browser).
• This payment method does not support refunds. It is recommended to communicate directly with the buyer offline.
• Obtain the payment result from the payment result notification (notifyPayment) or by making inquiries (inquiryPayment). Handle the redirection and display of the payment result page to avoid duplicate payments.

Default timeout

The QR code returned by Antom will not be refreshed automatically. When displaying the QR code, use the expireTime parameter value returned in the pay (Checkout Payment) API response to display the timeout information. When displaying the payment code, enable the copy function for the payment code and allow the buyer to conveniently paste the payment code into the payment method app.
