Remarks

Library key parameter

The Library Key parameter value can be found if you access the Plex server from the Web app.

When you hover over any item - movie, TV show, music, photo, etc. there will be a key parameter in the URL. That key value is the value you will use for the Library Key parameter.

The value is easy to find in the URL of the item. It has the structure /library/metadata/{id}. You will use the entire value of the key parameter from the media item URL.
