Connections

Edit Connection Fields

  • Name: A unique name for your connection (min. 3 characters).
  • Arr Type: Select either Radarr or Sonarr.
  • Monitor Type: Choose how trailers are monitored/downloaded (see below).
  • Server URL: The full URL to your Radarr/Sonarr server (e.g., http://192.168.0.15:7878).

  • External URL: (Optional) If you access your Radarr/Sonarr instance through a reverse proxy or a different URL than the server URL, specify that here.

    This URL will be used by Trailarr when generating links to media items in the web interface.

    For example, https://arr.mydomain.com/radarr.

    External URL is only used for generating links in Trailarr Web interface. The Server URL is still used for API communication with Radarr/Sonarr.

  • API Key: The API key from your Radarr/Sonarr server settings.

  • Path Mappings: Map Radarr/Sonarr internal paths to Trailarr paths for correct file access.

Monitor Types

Missing

Monitors and downloads trailers for movies/series without a trailer.

New

Only Monitors and download trailers for movies/series that gets added after the change.

Sync

Monitors and downloads trailers for movie/series that are monitored in Radarr/Sonarr.

None

Turns off monitoring for the connection and does not download any trailers.

Tip

If you have a huge library and don't want to download trailers for all of them, set the monitor type to None when adding a Radarr/Sonarr Connection. Wait for an hour or so to let the app sync all media from that connection, and change it to New to download trailers for new media. You can always manually set the monitor type for the movies/series you want to download trailers for.

Plex Connection

v0.9.0

Plex connections work differently from Radarr/Sonarr connections. See Plex Connection Fields for a full field reference and Plex Connection Setup for a step-by-step guide.

Key differences:

  • Authentication: Uses OAuth (sign in with your Plex account) instead of an API key.
  • Library folders instead of path mappings: Maps Plex library folder paths to Trailarr container paths. The sync monitor option is not available.
  • No sync monitor type: Plex connections support missing, new, and none. The new option is disabled when first creating a connection.

You still need at least one Radarr or Sonarr connection — a Plex connection alone is not sufficient to use Trailarr.
