Behavior when "Cancel a payment API" is executed before payment
How long is the generated code valid?
I'm trying to call the PayPay payment screen in Webview, but it doesn't work properly.
How can I determine the success or failure of payment?
What happens if I read the QR code outside the PayPay app?
If the payment completed code is requested to be deleted, Will payment be canceled?
Is it possible to delete (disable) the generated code?
Is it possible to use the created Code multiple times?
Is there any recommended or deprecated browser for displaying PayPay Web cashier page on the browser?
A half screen "There is a possibility of duplicate payment" was displayed on the user's screen.
