Official document for CONSUMPTION_REQUEST - What kind of data we are receiving?

This documentation describes what kind of data we should be sending to Apple server, once we are receiving CONSUMPTION_REQUEST

https://developer.apple.com/documentation/appstoreserverapi/consumptionrequest

But, it doesn't describe what kind of data we are receiving, when we are receiving CONSUMPTION_REQUEST?

May I know, is such a document available?

Thank you.
