What is ZipZign?

ZipZign is a REST API for document workflows. Send it HTML, get back a signed PDF, a payment receipt, or both.

What you can do

Generate PDFs from HTML templates with dynamic data
Collect e-signatures from up to 6 signers per document
Collect payments before or after signing
Chain signing and payment together in a single document flow

Document types

Type	Description
`readable`	PDF generation only — no signatures, no payment
`signable`	Signature collection from one or more signers
`payable`	Payment collection, no signing required

A signable document can also include a payment object to create a sign-then-pay flow.

How it works

POST a document with HTML content and signer/payer details
ZipZign renders the HTML to PDF, sends emails to signers/payers
Signers sign via a hosted, mobile-friendly page
Payers pay via a hosted Stripe checkout
ZipZign webhooks notify your app at each step
You retrieve the final PDF with embedded signatures

Authentication

All requests require an API key in the Authorization header:

Authorization: Bearer YOUR_API_KEY

See Authentication & API Keys for setup details.

Compliance

ZipZign signatures are ESIGN and UETA compliant. Each signing event captures IP address, user agent, timestamp, and consent version. A SHA-256 hash of the final PDF is stored for tamper evidence, and any document can be verified publicly via GET /api/documents/:id/verify.
