I've got two music libraries (with source IDs 12 and 13).

I can get a list of all playlists for both libraries with:

curl "http://127.0.0.1:32400/playlists/all/?Plex-Token=abcdefghijkl"

However I cannot seem to get a list of playlists for just one library.

I've tried:

curl "http://127.0.0.1:32400/playlists/12/?Plex-Token=abcdefghijkl"

but that returned "Not found".

Undeterred, I tried looking in the output of /playlists/all/ to see if I could parse it to determine which library each playlist entry sits in but, at first glance, there doesn't appear to be any kind of way to differentiate between the two.

Can anyone help me get a list of the playlists just for a single library?
