Is there an existing issue for this?

I have searched the existing open and closed issues

I maintain a mirrored version of my music library in which any high-res tracks are downsampled to CD quality. I use this downsampled folder on my phone where hard drive space is an issue, whilst still having the highest quality version on my PC for when I'm listening at home.

I run a simple webhook server which listens for Lidarr events - principally "Download" events for when a release is imported to my music library and "AlbumDelete"/"ArtistDelete" for those self-explanatory events.

However, if I delete files in a particular release within the Lidarr UI (Manage Tracks > Delete), then the files are deleted from my primary music music library but no event is fired from Lidarr. As a result, my downsampled music library will fall out of sync because it doesn't know that the tracks have been deleted.

Is it possible to add an event for each track that is deleted from the Lidarr UI?

Describe the solution you'd like

A new "TrackDelete" event to be available.

Describe alternatives you've considered

Anything else?

EDIT: I had some errors in my script that was causing part of my issue, so I've updated this post and removed some things. The rest is still valid.

Yes, please. TrackDeleted event should be added for custom scripting. Better yet, the scope of this "Issue" should be expanded to include other oddities and missing elements from the Custom Script API.

There are missing environment variables for other events that make custom scripts impossible. Such as an album path for the AlbumDeleted event. I used printenv to a log file for debugging and found several environment variables and/or event types are not available or incorrect.

These should all be reviewed and corrected/implemented:

AlbumDeleted (needs album path at least)
ArtistDeleted
TrackDeleted (doesn't exist?)

When you delete an album, there is no album path for the AlbumDeleted event:
