Key Steps Description:

• Step 2 The merchant initiates the order from the backend and receives a payment link.
• Step 6 The merchant page can redirect to the payment link, and the user can proceed with the payment.
• Step 21 After the payment is completed, the merchant receives an asynchronous notification of the payment result. If not received (some payment types do not support asynchronous notifications), the merchant needs to actively query.
