Dealing with edge cases

Case 1 : The payment screen is closed before payment is completed.

Currently, Nodex Pay does not provide a function to invalidate a Payment once it has been generated. It means, if a payer reopens a closed payment screen, he/she can continue payment. Therefore, be sure to call the Payment Request API with one unique OrderCode per the payer's order.

Case 2 : The payment screen is closed during or after payment is completed using browser close button.

Nodex Pay sends a Kickback to the business client's Payment Result API when the payment is completed. The business client's site should determine whether or not the Kickback has been received to determine if the payment has been completed and to guide the payer to the business client's site.
