In the mobile ICBC Merchant Home, there is no voice prompt for payment, what should I do?

Guest Yang Wanwan had a roast duck meal in Quanjude, Beijing. When he checked out, he used a WeChat barcode to pay the bill of 990 yuan. After waiting for 3 minutes, the cashier still did not receive a successful payment result. Yang Wanwan: I’m afraid the payment didn’t go through successfully. I have to catch a flight. So he threw down the 1,000 yuan and hurried away randomly, "No need to look for it anymore." After getting off the plane at Shenzhen Airport, I could finally turn off airplane mode. "SMS message: Your China Merchants Bank card xxx will be deducted 990." "What the hell?" The roast duck is so unpalatable, why did you try to cheat me by 1,000 yuan more? It’s not that I’m short of money. I can’t bear to swallow this, so I’ll fly back to seek justice.”

Relying on the asynchronous callback of the payment result, the timeliness cannot be guaranteed. , the asynchronous callback delay may cause the customer to leave the store and the transaction result is not clear success or failure

2) Scenario 2: Dialogue

Service provider: WeChat Pay brother, you are my idol , your technology is so awesome, why don’t you give us asynchronous notifications, and let us poll you, how troublesome~

WeChat Pay: Children, please be patient, our big data center tells you 86.9876% of our face-to-face payment scenarios are completed instantaneously when the amount is less than 500 yuan. The payment interface is directly returned to you synchronously. What do you think of me if you ask me to make another asynchronous callback? Does the real body think that we people are stupid because we have too much money and too little life?

3) Scenario 3: Conversation

Service provider: WeChat payment brother, the customer Yang paid a million dollars more, so he flew all the way from Shenzhen back to Beijing to argue with Quanjude , but also to compensate for the round-trip air tickets and mental losses. The cashier in Quanjude was driven crazy and asked our service provider to compensate. We checked the logs and found out that your notification results arrived so late, 30 minutes late.

WeChat Pay: Don’t worry, I’ll check our logs. Blame me? Did you have any service issues during that time? Notified more than ten times and all read timeouts occurred.

Service provider: What do you think we should do? Compensate with us

WeChat Pay: Yes~, in the future we will not provide asynchronous callbacks to service providers. You can poll them yourself. The payment, query, and cancellation capabilities are provided to you. I will suggest an interaction for you. Please see our official documentation for the flow chart, it is seamless. You can play whatever you like, and I'm too lazy to talk to you about it.
