  The Au Pay API integration documentation introduces how to implement order creation and payment functions through API. It is suitable for merchants who need to support Au Pay payment methods in Japan region, providing server-to-server payment requests and redirect completion payment process. Key steps include calling the order creation and payment API and performing page redirection based on the returned paymentRedirectUrl to complete the payment.
