Right now when a series is download/imported/renamed that event can trigger an event to the webhook but nothing seems to be triggered if you move a series.
For things like Plex Autoscan that push scan requests to Plex from these webhooks, having a notification for a series being moved would be really useful even if it would normally be a rarity.
I noticed this as I’m in the process of migrating some shows to another file system but was not seeing the webhook get triggered.
I’m not sure how much work this would involve but I’d imagine it’s similar to a rename at least for Linux.
