PDFInvoiceAPI documentation

PDFInvoiceAPI is a single synchronous call:POST /v1/render. Send HTML (or a template plus data) and you get the raw PDF bytes back in the response. It runs on Cloudflare's edge, so there are no servers, browsers, or queues for you to operate.

How it works

Every request authenticates with a Bearer API key and returnsapplication/pdf directly — stream it to a file, a browser, or storage. Each successful render costs one credit. Here's the whole thing:

curl https://api.pdfinvoiceapi.com/v1/render \
  -H "Authorization: Bearer sk_live_..." \
  -H "Content-Type: application/json" \
  -d '{ "html": "<h1>Invoice #1024</h1><p>Total: €1,240.00</p>" }' \
  -o invoice.pdf

Two ways to render

• Raw HTML — pass a self-containedhtml string. See Rendering HTML.
• Templates — pass an inline template with{{ }} placeholders plus data, or a stored template id (tpl_…) you save once and render by id. SeeTemplates.

Control page size, margins, and orientation withPDF options. On paid plans the rendered PDF is clean — see Remove branding.
