Paperless Invoicing

설명

Paperless Invoicing connects WooCommerce to the Paperless API.

When an order reaches the Completed status, the plugin sends invoice payload data to:
https://api.paperless.tax/invoices/api/create

On success, the returned invoice URL is saved on the order and displayed to the customer on:
– Thank You page
– My Account -> Order details

The plugin is built for a behind-the-scenes checkout flow: customers place orders normally, while invoice creation happens automatically in the background.

Key Features

  • Automatic invoice creation when order status becomes Completed
  • Hardcoded Paperless endpoint for production use
  • API key authentication via X-API-KEY header
  • Product-level mapping with Paperless Product ID
  • Invoice URL persistence in order meta
  • Customer-facing invoice link display (Thank You + My Account)
  • Error logging to WooCommerce logs (source: paperless-invoicing)

Notes

  • Trigger status is fixed to Completed.
  • Invoice type is fixed to 2 (InvoiceReceipt).
  • Plugin does not send invoice emails.
  • To avoid duplicates, there is no manual retry action in order actions.
