Plex Integration

Bazarr integrates with Plex Media Server to enable automatic subtitle management and workflow automation. The integration supports OAuth authentication (default) and legacy API key configuration.

It should be noted that this functionality is available from Bazarr version 1.5.3 and onwards - and still needs Sonarr and Radarr to function.

Features

  • OAuth Authentication - Secure token-based authentication with automatic server discovery
  • Library Updates - Refresh specific items after subtitle changes
  • Added Date Updates - Set movie and episode added dates automatically
  • Webhooks - Real-time subtitle search on media playback (Plex Pass required)
  • Automatic Migration - Seamless upgrade from API key to OAuth authentication

Authentication Methods

OAuth Authentication (Default)

OAuth is the default authentication method available through the web interface.

Benefits:

  • Secure PIN-based authentication flow
  • Automatic server discovery and testing
  • Encrypted token storage with URLSafeSerializer
  • No manual API key retrieval required

Requirements:

  • Internet connection during setup
  • Web browser with popup windows enabled
  • Plex account with server access

API Key Authentication (Legacy)

API key authentication is legacy and should be avoided. It's available only through manual config.yaml configuration for existing setups.

Configuration:

plex:
  auth_method: apikey
  ip: 192.168.1.100
  port: 32400
  ssl: false
  apikey: your-plex-token-here
  movie_library: Movies
  series_library: TV Shows

Requirements:

  • Manual config.yaml editing
  • Manual API key retrieval

Setup

Enable Plex Integration

  1. Navigate to Settings → General
  2. Enable Use Plex
  3. Save settings

OAuth Configuration

  1. Go to Settings → Plex
  2. Click "Connect to Plex"
  3. Complete authentication in popup window
  4. Select server (if multiple servers available)
  5. Configure movie and TV libraries

Server Selection

  • Single server: automatically selected
  • Multiple servers: choose from dropdown and click "Select Server"
  • Connection testing performed automatically

Library Configuration

  • Libraries automatically fetched from selected server
  • Only movie and show libraries displayed
  • Select one library per content type

Settings Reference

Setting Description OAuth API Key
Authentication Method OAuth (web UI) / apikey (config) Default Manual
Server Discovery Automatic with testing Yes Manual
Token Storage Encrypted with URLSafeSerializer Yes Yes
Library Fetching Automatic from server Yes Manual

Integration Options

Feature Description
Set Movie Added Date Update added date when subtitles found
Set Episode Added Date Update added date when subtitles found
Update Movie Library Refresh specific movies after changes
Update Series Library Refresh specific episodes after changes

Webhooks

Plex webhooks enable real-time subtitle search when media is played. Webhook creation and management is automated through the Bazarr UI.

Requirements:

  • Plex Pass subscription
  • Configured Plex integration
  • Bazarr API key

Webhook URL Format:

http(s)://your-bazarr-url/api/webhooks/plex?apikey=your-bazarr-api-key

Webhook Management:

  • POST /api/plex/webhook/create - Create webhook automatically
  • GET /api/plex/webhook/list - List existing webhooks
  • POST /api/plex/webhook/delete - Delete webhook

Migration

Automatic Migration (Default)

Bazarr automatically migrates API key configurations to OAuth on startup.

Process:

  1. Detects existing API key configuration
  2. Creates backup of current settings
  3. Validates OAuth configuration
  4. Preserves library names and settings
  5. Implements rollback on failure

Safety Features:

  • Configuration backup before changes
  • Validation before permanent changes
  • Graceful rollback on failure
  • Migration attempt tracking

Manual Migration

If automatic migration fails:

  1. Note current server IP, port, and library settings
  2. Enable OAuth in settings
  3. Complete OAuth authentication
  4. Select matching server
  5. Verify library configuration
  6. Test functionality

Troubleshooting

OAuth Issues

Authentication Fails:

  • Check internet connectivity
  • Verify popup windows aren't blocked
  • Clear browser cache
  • Verify Plex account server access

Server Not Found:

  • Verify Plex server is online
  • Check server account association
  • Ensure remote access if needed

Token Errors:

  • Re-authenticate with OAuth
  • Check if Plex password changed
  • Clear Bazarr Plex settings

API Key Issues

Connection Timeouts:

  • Verify IP address and port
  • Check network connectivity
  • Ensure Plex server is running

Invalid Token:

  • Regenerate Plex token
  • Verify token permissions
  • Check Plex account status

Library Not Found:

  • Check exact library names
  • Verify library permissions
  • Check Plex server logs

Debug Logging

  1. Settings → General → Logging
  2. Set log level to DEBUG
  3. Reproduce issue
  4. Check Settings → System → Logs

API Reference

OAuth Endpoints
