The payment method is JSSDK to complete the payment call. In addition, you need to complete the payment-related configuration with the service number. In addition, there are two kinds of notification for successful payment: synchronous notification (100% is not guaranteed to be completely correct) and asynchronous notification (ensure that the payment status is completely correct). The asynchronous notification URL passes the URL to the server before calling the interface.
The technical process is roughly as follows: the backend language SDK initializes and calls the API, assigns a value to the template, then calls JSSDK to initiate a payment, completes the payment, and synchronizes the prompt of JSSDK Call Notification Method completion, asynchronous interface notification ensures full synchronization of order status and payment
