Radarr Integration

Discarr notifies Radarr when a movie encode completes so it can trigger an import scan automatically.

1. Add the notification hook

In Radarr, go to Settings → Connect → Add Connection → Custom Script.

Field Value
Name Discarr
Path /opt/discarr/scripts/radarr-notify.sh
On Import
On Movie File Delete

2. Configure the API key

In ~/.config/media-postprocessor/api-keys.conf:

RADARR_URL=http://your-radarr-host:7878/radarr
RADARR_API_KEY=your-radarr-api-key

Find your API key in Radarr under Settings → General → Security → API Key.

3. How it works

Encode completes
      │
      ▼
radarr-notify.sh
      │  POST /api/v3/command
      │  {"name": "RescanMovie", "movieId": <id>}
      ▼
Radarr imports file

4. Test the connection

Click Test on the connection in Radarr. To test end-to-end, queue a movie encode in Discarr and watch Activity → Queue in Radarr for the import.
