Connections

Edit Connection Fields

  • Name: A unique name for your connection (min. 3 characters).
  • Arr Type: Select either Radarr or Sonarr.
  • Monitor New Media: Whether media added by this connection start monitored (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 New Media

v0.10.2

This Yes/No toggle decides the starting monitor state for media added by this connection: Yes → new media start monitored (a trailer will be downloaded for them), No → new media start unmonitored. It applies only once, when a media item is first added — after that, monitoring belongs entirely to you: change it per item (or in bulk) from the library pages, and nothing changes it back. Connection syncs and downloads never touch it.

Upgrading from Monitor Types

Before v0.10.2 this was a four-value Monitor Type dropdown (Missing / New / Sync / None). Existing connections migrate automatically: None becomes No, everything else becomes Yes — and your media keep their current monitor values. If you used Sync, Trailarr no longer follows monitoring changes from Radarr/Sonarr; to keep sync-like behavior, add a profile filter on arr_monitored instead — see Sync-like behavior with arr_monitored. The upgrade logs list your affected connections.

Tip

If you have a huge library and don't want to download trailers for all of it, set Monitor New Media to No when adding the connection. Wait for the first sync to finish, then flip it to Yes — only media added from then on start monitored. You can always monitor individual movies/series by hand from the library.


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.
