# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Project Overview

This is a Python automation script that downloads Amazon order invoices in bulk using Selenium WebDriver. It reads order IDs from [orders.txt](orders.txt) and automates the process of navigating to invoice pages and triggering the print dialog for each order.

## Dependencies

- Python 3.x with `selenium` package
- Chrome browser with ChromeDriver
- Virtual environment in `venv/` directory

## Running the Script

1. Activate the virtual environment:
   - Windows: `venv\Scripts\activate`
   - Unix/macOS: `source venv/bin/activate`

2. Run the script:
   ```
   python invoices.py
   ```

3. When prompted, manually log into Amazon in the browser window, then press Enter in the terminal to continue

4. The script will iterate through each order ID in [orders.txt](orders.txt) and open the print dialog for the invoice

## Input Format

[orders.txt](orders.txt) should contain one Amazon order ID per line (format: `XXX-XXXXXXX-XXXXXXX`)

## Architecture Notes

- The script uses direct URL construction to access invoice print pages: `https://www.amazon.com/gp/css/summary/print.html?orderID={order}`
- Manual authentication is required due to Amazon's login protections
- 3-second delay between orders to avoid rate limiting
- Print dialog is triggered via JavaScript (`window.print()`) - user must manually save each PDF
