Document generation API — EU-hosted

Every business document. One API call away.

How it works

Three steps from data to document. No PDF libraries, no layout code, no printers.

01

Pick a template

Browse 49 packs — Belgian accounting, employment law, GDPR, payroll and more. Every template ships with a JSON schema and sample data.

02

Send your data

POST /render with your JSON. The API validates it against the template schema before anything is rendered.

03

Get a signed PDF

A professional, deterministic PDF comes back in seconds. Embed it, archive it or send it.

curl
curl -X POST https://api.papii.eu/render \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "template": "be.accounting.invoice",
    "data": { ... },
    "options": {"language": "fr"}
  }' -o invoice.pdf
