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. Map disc titles to movies¶

When you scan a disc in Discarr, each title needs to be mapped to a Radarr movie before it can be queued for encoding.

Browse Radarr movies¶

Click Browse Radarr to open your movie library, then use the search box to filter by title:

Radarr browse panel — search box filtering results to show matching movies

Select and map¶

Click the movie to select it. The title card on the left automatically links to the selected movie:

Radarr movie selected — disc title mapped to Crouching Tiger, Hidden Dragon

Drag a title to confirm the mapping¶

Drag the title card from the left panel and drop it onto the matching movie slot on the right. A green border confirms the mapping:

Title mapping complete — disc title dragged to movie slot, Review & Queue button active

Once all titles are mapped, click Review & Queue → to start encoding.

4. How it works¶

5. 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.
