Purchase order PDF API

A standard purchase order with vendor, ship-to and line items — issued automatically from your procurement system.

Issue purchase orders straight from your procurement or ERP system. Pass the buyer, vendor, ship-to and line items, and PDFgen returns a standard PO PDF with the order total formatted in — no manual document assembly.

One reusable template covers every supplier, so you can automate PO creation across your whole purchasing workflow.

Generate a Purchase Order PDF via the API

POST your data to /api/v1/generate and get a PDF back. Copy-paste an example, swap in your API key, and loop over a list to render thousands — one purchase order per record.

Frequently asked questions

Can I generate a PO directly from my ERP?
Yes — make a single POST to /api/v1/generate with the order data from your system and store or email the returned PDF.
Does it support separate vendor and ship-to addresses?
Yes — the template has distinct vendor and ship-to blocks, plus a line-item table with quantity, unit price and line totals.
Can I add PO terms or approval signatures?
Edit the template to include payment terms, notes or a signature line, then every PO renders with them.
