Amazon doesn't expose a public API for personal purchase history, so you need to
request a data export:

1. Open Amazon's data request page: [{AMAZON_REQUEST_URL}]({AMAZON_REQUEST_URL})
2. Select **Your Orders** and submit the request
3. Wait for Amazon to email a download link (typically a few hours to a few days)
4. Upload the resulting `Your Orders.zip` above
