Payment Process

1. The user places an order on the merchant's website and selects SPEI for payment;

2. The merchant initiates an SPEI payment request to Supefina;

3. Supefina returns the payment reference (CLABE account) information; When "checkOut" is "true", it will return the cashier page with the CRABE account number, and when "checkOut" is "false", it will only return the CRABE account number;

4. The merchant will show the payment reference (CRABE account) to the user;

5. The user copies the payment reference (CLABE account number);

6. The user opens the bank APP and selects the transfer, and enters the copied payment reference (CRABE account number) and amount to complete the transfer;

7. Supefina notifies the merchant that the order is successful.

Callback notification response

After the merchant successfully receives the callback, it needs to return the specified string synchronously: SUCCESS does not return or returns other content by default, and the notification fails As:

public String test(){
	return "SUCCESS";
}

note

After the user pays the payment, the payment system will send the relevant payment result to the merchant in the form of a data stream, and the merchant needs to receive and process it and return a reply according to the document specification.

1. The same notification may be sent to the merchant system multiple times. The merchant system must be able to handle duplicate notifications correctly.

2. When the background notification is interacted, if the payment system receives the merchant's reply that does not meet the specifications or times out, the payment system will judge that the notification fails and resend the notification (in the case that the notification has been unsuccessful, the payment system will launch multiple notifications in total, and the notification frequency is 0min/3min/6min/9min/12min), but the payment system does not guarantee that the notification will be successful in the end.

3. If the order status is unclear or the payment result is not notified, it is recommended that the merchant call the [Query API] to confirm the order status.

4. Duplicate payments, there are multiple payments in SPEI, please be aware of the situation where multiple payment notifications are received. For multiple payments, Supefina will create multiple orders and notify the merchant multiple times, and the merchant can determine whether it is the same order through the supefinaOrderId in the notification. The identifier remains unchanged when making multiple payments, and the supefinaOrderId and reference are different each time (HSBC banks have multiple payments with the same reference)
