Build a scan-to-link page on the client

Build the scan-to-link page

Display the authorized payment methods that you offer to buyers on the scan-to-lnk page.
Client

Payment

First-time payment

Obtain the authorization QR code

The first-time payment required the authorization from the buyers. After the buyer selects the payment method for authorization, you send an authorization inquiry request containing the relevant payment method information and retrieve the authorization QR code link from the response.
Client

Dispay the QR code

Display the QR code on the front-end page.
Client
Subsequent payments
Subsequent payments do not require buyer authorization and the back-end payment will directly return the payment information to the front-end after processing the payment.
Client


Checking the order status

The front-end queries the order status through polling or a long connection. The order is initialized during the authorization inquiry and the status is updated after the buyer authorizes the payment.
