PDF generation API: REST endpoint, CSV batch, no-code templates
Paperless gives you a REST API for branded PDF generation - call it from your backend, scheduled job or automation tool. Templates are designed visually by your team, and monthly generation limits depend on the plan. Enterprise deployments can be sized for higher volume.

The problem
Why teams move to a real PDF API
- Generating PDFs server-side from HTML is fragile and slow at scale.
- Headless Chrome / Puppeteer breaks on every Chrome update.
- Word + mail merge can't be triggered reliably from a backend job or API call.
- Existing PDF SaaS APIs charge per document - costs spike with growth.
- Designers and developers can't agree on the same template format.

FAQ
Common questions
Is there a free tier?
+
Yes. Paperless has a generous free tier with no credit card required. You can start generating PDFs from the API in minutes.
How do I authenticate API calls?
+
Each workspace can create multiple workspace-level API keys and rotate them when needed.
What goes into the API call?
+
JSON: a template ID and a data object. Paperless merges your data into the template and returns the PDF (or a URL to it). Sub-second response on the free tier.
Can I generate PDFs in batch?
+
Yes - upload a CSV and generate documents in batches. Batch output counts toward your plan's monthly document limit; enterprise plans can be sized for higher monthly volume.
Is Paperless self-hostable?
+
Yes - we offer self-hosted Paperless for enterprise clients with strict data residency requirements. Talk to us.
