A simple Flask application that sends notifications to Telegram whenever new content (movies, series, seasons, episodes) is added to Jellyfin.

---

• A Telegram bot token and chat ID (see the section on setting up a Telegram bot below).
• Docker (optional, for Docker installation).

Installation

1. Clone the repository.
2. Install the requirements using pip install -r requirements.txt.
3. Set up your environment variables. (TELEGRAM_BOT_TOKEN, TELEGRAM_CHAT_ID, JELLYFIN_BASE_URL, JELLYFIN_API_KEY, YOUTUBE_API_KEY, EPISODE_PREMIERED_WITHIN_X_DAYS, SEASON_ADDED_WITHIN_X_DAYS).
4. Run the application using python3 main.py.

Setting Up a Telegram Bot

1. Start a Chat with BotFather on Telegram.
2. Send /newbot command.
3. Name your bot.
4. Choose a unique username for your bot; it must end in bot.
5. Retrieve your HTTP API token.
6. Get your chat ID by starting a chat with your bot, sending a message, then visiting https://api.telegram.org/botYOUR_BOT_TOKEN/getUpdates to find the chat ID in the returned JSON.

Usage

Setting up Jellyfin Webhook

1. Go to Jellyfin dashboard.
2. Navigate to Plugins.
3. Choose Webhook and add a new webhook.
4. Set the server to the Flask application's endpoint (e.g., http://localhost:5000/webhook).
5. For Notification Type, select Item Added.
6. For Item Type, select Movie, Episode, Season.
7. Make sure to enable the Send All Properties (ignores template) option.

Environment Variables Explanation:

• EPISODE_PREMIERED_WITHIN_X_DAYS: Determines how recent an episode's premiere date must be for a notification to be sent. For example, setting it to 7 means only episodes that premiered within the last 7 days will trigger a notification.

• SEASON_ADDED_WITHIN_X_DAYS: Dictates the threshold for sending notifications based on when a season was added to Jellyfin. If set to 3, then if a season was added within the last 3 days, episode notifications will not be sent to avoid potential spam from adding an entire season at once.

Setting Up YouTube API Key (Optional)

If you want to fetch YouTube trailer URLs for movies, you can set up a YouTube API key:

1. Go to the Google Cloud Console.
2. Create a new project or use an existing one.
3. Enable the "YouTube Data API v3" for your project.
4. Create credentials for your project:
   • Go to the "Credentials" tab.
   • Click on "Create Credentials" and select "API Key".
5. Copy the generated API key.
6. Set the YOUTUBE_API_KEY environment variable in your .env file to the copied API key.
