# Amazon Kindle Email PDF Downloader

This project is a Python daemon that connects to your Gmail account, searches for unread emails from "Amazon Kindle Support" containing PDF download links, and automatically downloads the PDFs to a specified local directory if they don’t already exist. The script runs as a background service and checks for new emails at a specified interval.

## Features
- Automatically reads unread emails from Gmail.
- Searches for emails from "Amazon Kindle Support" with PDF download links.
- Parses the email to extract the actual PDF download link.
- Downloads the PDF file and saves it to a local `data` directory.
- Runs as a daemon, checking for new emails periodically.

## Requirements
- Python 3.7+
- Google API credentials for Gmail API access
- Gmail API access enabled in Google Cloud Console

## Installation

1. **Clone the Repository**:
   ```bash
   git clone https://github.com/yourusername/amznMailConverter.git
   cd amznMailConverter
   ```

2. **Install Dependencies**:
   ```bash
   pip install -r requirements.txt
   ```
   The `requirements.txt` should include:
   ```plaintext
   google-auth
   google-auth-oauthlib
   google-auth-httplib2
   google-api-python-client
   requests
   beautifulsoup4
   python-daemon  # Only if using the daemon library
   ```

3. **Set Up Google API Credentials**:
   - Create a project in the [Google Cloud Console](https://console.cloud.google.com/).
   - Enable the Gmail API.
   - Download the OAuth 2.0 Client Credentials JSON file, rename it to `credentials.json`, and place it in the project root directory.

4. **Authorize Access**:
   - On first run, the script will prompt you to authorize Gmail API access. Follow the instructions in the browser to grant permissions.
   - After authorization, a `token.json` file will be generated to store your access token.

## Usage

To run the script as a daemon, use one of the following methods:

### 1. Using Python Daemon Library (Recommended for Simplicity)

```bash
python3 email_pdf_downloader.py
```

The script will run in the background, checking for new emails every 5 minutes.

### 2. Using Systemd (Linux)

1. **Create a Systemd Service**:
   - Create a file `/etc/systemd/system/email_reader.service`:
     ```ini
     [Unit]
     Description=Email PDF Downloader Daemon

     [Service]
     ExecStart=/usr/bin/python3 /path/to/email_pdf_downloader.py
     Restart=always
     User=your_username
     WorkingDirectory=/path/to/project

     [Install]
     WantedBy=multi-user.target
     ```

2. **Enable and Start the Service**:
   ```bash
   sudo systemctl daemon-reload
   sudo systemctl enable email_reader.service
   sudo systemctl start email_reader.service
   ```

3. **Check Status**:
   ```bash
   sudo systemctl status email_reader.service
   ```

## Configuration
- **SCOPES**: OAuth scopes for Gmail API access.
- **SEARCH_QUERY**: Query to filter emails by sender ("Amazon Kindle Support").
- **SCRIPT_DIR**: Base directory where files are saved.
- **Interval**: The script is set to check for new emails every 5 minutes (300 seconds). You can adjust this interval in the `run_daemon` function in `email_pdf_downloader.py`.

## Logging
Logging information (success messages, errors) is printed to the console or saved to `systemd` logs when running as a systemd service.
