REST order → mill JSON
WooCommerce packing slip API
Headless or custom Woo. Map the REST order. POST JSON. No Dompdf on the shop.
This is not a WooCommerce plugin and not an official extension. It is the same packing slip PDF API with Woo-shaped order data on your side of the wire.
Pull the order from the Woo REST API or from your existing fulfillment job. Map billing, shipping, and line items into the packing-slip schema. Render. You do not install Dompdf, mPDF, or a PHP HTML renderer on the shop.
If you also need an invoice PDF, use template invoice on the same key. Cents as sent. No tax engine.
