In-store Payment

📄️ QR Pay(Merchant-presented)

The merchant backend calls this API to create a prepayment transaction on PayCloud. PayCloud returns the QR code image link, and customers can complete the payment by scanning the QR code using their mobile wallet.

📄️ In-store Mobile Web Payment

The merchant calls this API in offline scenarios to generate a pre-payment transaction order in the PayCloud service backend and initiates web payment based on the returned checkout URL or payment parameters.

📄️ QR Pay(Customer-presented)

After the cashier uses the scanning device to read the payment code from the user's wallet app, the QR code or barcode information is sent to the merchant’s cash register. The merchant’s cash register or backend will then call this API to initiate the payment.
