If there is a payment request for the same merchant and the same amount of money multiple payment within a short period of time, PayPay will perform checks to prevent unintended double payments.
Note1:If you want to carry out a payment with the same content in a short period of time with native payments, set the value of agreeSimilarTransaction to true and execute the payment request.
Note2: There is no way to avoid SUSPECTED_DUPLICATE_PAYMENT for continuouspayment. Therefore, please handle this in the merchant's implementation.
