Radarr & Sonarr Integration

Radarr and Sonarr are optional metadata integrations.

They are not required for media scanning, profanity detection, or CLEAN audio creation.

What they add

Radarr

  • movie posters
  • richer movie metadata
  • association between Censorarr files and Radarr movie entries

Sonarr

  • series/season/episode metadata
  • richer TV Shows page

Without them, Censorarr falls back to the mounted folders.

Radarr example

arr_integrations:
  radarr:
    enabled: true
    url: http://RADARR-SERVER-IP:7878
    path_mappings:
      - from: /movies
        to: /media

Save the Radarr API key in Censorarr Settings.

Sonarr example

arr_integrations:
  sonarr:
    enabled: true
    url: http://SONARR-SERVER-IP:8989
    path_mappings:
      - from: /tv
        to: /tv

Save the Sonarr API key in Censorarr Settings.

Path mapping rule

The mapping is:

from = path the *arr application reports
to   = equivalent path inside Censorarr

Example:

Radarr reports:

/movies/Alien (1979)/Alien.mkv

Censorarr sees:

/media/Alien (1979)/Alien.mkv

Use:

- from: /movies
  to: /media

Common mistake

Do not assume the NAS path must match between containers.

Container paths are allowed to differ as long as the mapping accurately translates them.

Testing

Use the integration test button in Censorarr Settings after entering:

  • URL
  • API key
  • path mapping

If the connection test passes but media associations are wrong, the path mapping is the next thing to check.
