What it does

This program amazon-invoice-downloader.py is a utility script that uses the Playwright library to spin up a Chromium instance and automate the process of downloading invoices for Amazon purchases within a specified date range. The script logs into Amazon using the provided email and password, navigates to the "Returns & Orders" section, and retrieves invoices for the specified year or date range.

The user can provide their Amazon login credentials either through command line arguments (--email= --password=) or as environment variables ($AMAZON_EMAIL and $AMAZON_PASSWORD).

The script accepts the date range either as a specific year (--year=) or as a date range (--date-range=). If no date range is provided, the script defaults to the current year.

Once the invoices are retrieved, they are saved as PDF files in a local "downloads" directory. The filename of each PDF is formatted as YYYYMMDD_<total>_amazon_<orderid>.pdf, where YYYYMMDD is the date of the order, total is the total amount of the order (with dollar signs and commas removed), and orderid is the unique Amazon order ID.

The program has a built-in "human latency" function, sleep(), to mimic human behavior by introducing random pauses between certain actions. This can help prevent the script from being detected and blocked as a bot by Amazon.

The script will skip downloading a file if it already exists in the ./downloads directory.

Installation

pip install amazon-invoice-downloader
playwright install
