I'm curious. In the addon we use addon callbacks. onNotification is returning information for this case. Isn't is possible to "monitor" those notifications by core for your case, too?

Code:

sender xbmc - method: VideoLibrary.OnUpdate  - data: {"item":{"id":13,"type":"movie"},"playcount":1}

In theory yes but then every media importer add-on would have to decide on its own whether it is responsible for sending these updates back to a specific server. But there might be multiple add-ons installed which could do this so we make this decision in Kodi and explicitly tell a specific add-on to do it.

But this doesn't change the fact that we need to have specific API methods in Emby server to perform these actions independent of how the add-on becomes aware of an update.
