How it works

From data to filed document in minutes

No browser automation to maintain and no print pipeline to babysit — design or import once, then generate signed, verifiable PDFs from a single API call.

1. Design or import

Build a template in the visual editor, or drop in an existing PDF and bind your data fields.

2. Call the API

POST your JSON to /v1/render — add signing, PDF/A, or async delivery in the same call.

3. Get a verifiable PDF

Receive a signed, archival PDF — multi-page invoices included — plus a provenance hash anyone can verify against the original.

Platform

A complete toolkit for document automation

From a visual designer to signed, verifiable output, ApiForm covers the full lifecycle of a generated document — so you ship one integration, not a print pipeline.

Make any PDF fillable

Turn a flat government form or invoice into real interactive fields — draw them yourself, or let line detection and Claude vision detect and name them for you.

Visual template designer

Design pixel-perfect templates and bind JSON with live expressions, or import an existing PDF and map your data to it.

Schedule

Tomorrow 8:30 pm is our priority.

Line items that just work

Feed an array, get an invoice: rows paginate onto continuation pages with headers repeated and totals on the last page — 3 items or 40, same template. Over-limit data fails loudly, never silently clipped.

Async jobs & webhooks

Render in batches at scale and get signed webhook callbacks the moment long-running jobs finish.

What you get

Output that stands up to scrutiny

Generic PDF tools stop at rendering. ApiForm makes every document provably yours — signed, archival, and verifiable long after it's filed.

Signed & sealed

Add a PKCS#7 digital signature to any render — or bring your own certificate on Enterprise so signatures chain to your identity.

Verifiable by anyone

A public verify endpoint confirms a PDF matches the original data, template, and signature — byte‑for‑byte, months after it shipped.
