Amazon Punch out - Submit purchase order data

Summary:

When conducting a punch-out with Amazon, I believe that it is necessary to send the approved purchase order data to Amazon, but I am not sure what specific method is used to send the purchase order data to Amazon. I want you to tell me.

As a result of our inquiries in SR, we received a response that it is possible to send purchase order data to Amazon by using the Collaboration Messaging Framework "Purchase Order Outbound Message". Please let me know if you have any experience of actually transmitting data using this method.
