Usage Examples

Adding an Album

To add an album to your Lidarr library, you need to use a two-step process:

1. Lookup: Use the Album Lookup operation to search for the album you want to add

   • Set Resource to "Album"
   • Set Operation to "Lookup"
   • Enter your search term (e.g., "Dark Side of the Moon Pink Floyd")
   • This returns results with foreignAlbumId (MusicBrainz ID)

2. Create: Use the Album Create operation to add the album

   • Set Resource to "Album"
   • Set Operation to "Create"
   • Enter the foreignAlbumId from the Lookup result
   • Optionally set Artist ID, Monitored status, and other options
   • Set "Search for New Album" to true to automatically search for the album after adding

The same workflow applies to adding artists (Artist Lookup → Artist Create).
