## Description

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.
