What kind of API response is returned when I try to make a payment to a user whose valid period for user authorization has passed?
How long is the user authorization valid?
How do I get the user authorization scope?
Is it possible to cancel the link with PayPay from the service side of the merchant?
If the user does not have a PayPay account, can I register a new one on the user authorization acquisition web page?
Is it possible to cancel the connection between the user and PayPay from the merchant side?
If It perform Acquire user authorization multiple times with the same PayPay user, does userAuthorizationId change each time?
