Final payment instruction: When all the checks above have been completed, there is a much higher degree of confidence that the payment will successfully complete. The payment instruction can now be sent from the Source Bank to the Source IPS. Once the payment is complete in the Source IPS, the Nexus Gateway will communicate with the Nexus Gateway in the Destination Country, who will trigger the second stage of the process in the Destination IPS. Once this stage is complete, the Recipient will be credited and notified, and the Sender will be notified that their payment was successful. (This instruction is sent directly to the Source IPS in the local message format, so does not use a Nexus API.)
