System failure -> stocks, orders, mails desynchronized
-
The case is as follows:
– The customer places an order on “THESITE” and is then directed (throught a gateway “Payline”) to a payment server “HEREWEPAY” to process his payment.
– Just after the payment is correctly performed and validated by the payment server “HEREWEPAY”, that one can not properly return to “THESITE” because there is a “THESITE” failure.
– Finally the customer succeeds to connect again to “THESITE” and see that all is OK : his order is recorded in a “processing” status.However, the situation is not synchronous because:
– OK: The site manager has received the email stating that a new order was post.
– OK: The customer’s order is recorded in the “processing” status and will be processed and shipped.
– NOK: The customer has not received the email stating that its order was correctly registered (no notes).
– NOK: The product stock has not been decreased.How can these actions be asynchronous (all or none performed)? Is there a solution to prevent?
