CollectAsynchronousNotifications

CollectAsynchronousNotifications

• Please note: The current collection service will only have a callback notification when the order is successfully paid
• When verifying the signature, you need to use the platform public key provided in the merchant background - payment collection and payment configuration - API configuration for decryption!!
• AFTER ACCEPTING THE ASYNCHRONOUS NOTIFICATION, YOU RESPOND WITH THE SUCCESS STRING
• Otherwise, TopPay will continue to send out 5 notifications
