Slipmill

From the warehouse, not the designer

Print packing slips programmatically

A fulfillment worker should print a slip without opening a browser. POST JSON. Print the PDF. Ship the box.

Programmatic printing means your pack station, 3PL, or fulfillment job calls an API and gets bytes. Slipmill returns application/pdf synchronously. You send those bytes to a printer, a pack-slip folder, or a carrier attachment.

Step four is the outcome: print it or attach it to the shipment. The mill does not talk to the printer. You do.

No silent Gmail login. No dashboard you must click through to get a PDF. A key in a header is the whole auth story.
