How to configure the webhook to send just the document changes on the latest revision?

This is my scenario so that the client is offline and update the document “n” times then when it’ll back online, on the server I would like to configure the webhook to send just the changes on the latest revision of that document , is this possible?

In case not from the .Net SDK there is a way to check if what the webhook sent to me is the latest version of the document? If yes how can I do it?

Any advice is more than welcome
