How to create a workflow for both payments conform and payments failed

[Aspiringtoddlers]

how to send messages for both payment conformation and payment failed, for payment conformation, a conformation message should be sent and for failed payment, a failed payment message should be sent with a delay, and in case the customer payment is failed for the first time and then he tries again and the payment is success then only payment success message should be sent.
