   • Use tab completion to select categories
   • Accept suggested memos or customize them
   • Confirm updates with enhanced previews

Keyboard Shortcuts

Security Notes

⚠️ Important: Never commit your .env file to version control!

• The script loads credentials from environment variables or config file
• Your API key is never hardcoded in the script
• Add .env to your .gitignore if using git

Troubleshooting

"No orders could be parsed"

• Make sure you're copying the full Amazon orders page content
• Try copying from a different browser or clearing browser cache

"API Key not found"

• Verify your .env file exists and has the correct format
• Check that your API key is valid in YNAB Developer Settings

"No transactions found"

• Ensure you have uncategorized Amazon transactions in YNAB
• Check that the payee names contain "amazon", "amzn", or "amz"

Emoji display issues

• Use python -X utf8 on Windows for proper emoji support
• Ensure your terminal supports UTF-8 encoding
