Thanks for the additional FR @atyaglik! We don’t currently document dedicated webhook topics for Files API events like files/create, files/update, or files/delete.
The current documented path is to query the Files API and check fileStatus where processing state matters. Product or collection webhooks can help with some resource-specific media changes, but they don’t provide full file-level coverage for changes made directly in the Files section, so I agree that isn’t a complete workaround for your sync use case.
I’ve captured this as product feedback internally. I can’t promise if or when new topics will be added, but this is a clear gap for apps that need real-time media-library synchronization. Thanks for posting!
