}'One call creates the signature request. IgniSign emails the signer or you embed the signing page; a webhook tells your backend when the proof is ready.
IgniSign is an e-signature API for developers and integrators. Your application creates a signature request, the signer signs inside your product or from a link, and you keep the proof: a signed PDF, signature files and an audit log. Simple and advanced electronic signatures as defined by eIDAS, billed per signature, with a free development environment.
An embedded signing page in your application, a hosted link IgniSign sends by email (BySide), or a hash-only bare signature for documents that never leave your systems.
A signed PDF with its signature page, the signature files and a timestamped audit log, for every signature request — and a webhook when it is done.
Development is free. In production you pay per signature, invoiced monthly in arrears.
One call with the document, the signers and the signature profile. Your development API key works from day one.
In your application, in the page IgniSign hosts, or through a bare signature on a hash. Email, SMS code, TOTP, passkey or your SSO as authentication.
Signed PDF, signature files and audit log, from the API or the console.
| Level | Authentication | Identity | Proof |
|---|---|---|---|
| Simple electronic signature | One factor: an email link (BySide) or a signer secret held by your application (embedded). | Declared by the requester. | Signed PDF, signature files, audit log. |
| Advanced electronic signature | Two factors: plus a one-time SMS code, TOTP or passkey. | Verified — by the second factor registered at identification, or by an automated ID document and selfie check, open banking or SSN. | Signed PDF, signature files, audit log with the identity and authentication evidence. |
IgniSign does not offer qualified electronic signatures. Both levels are electronic signatures as defined by the eIDAS regulation; their legal effect depends on the applicable law and on your use case.
Every signature produces a signed PDF with a signature page, the signature files and a timestamped audit log. Retrieve them from the API or the console — the proof is yours to store.
Signature proofs →So that you do not spend a week integrating the wrong tool.
- Not a qualified trust service provider, and not a qualified electronic signature product.
- Not an eID provider — identity verification uses an automated ID document check, open banking or SSN.
- Not a contract-lifecycle, document-management or board-portal tool.
- Not a web console for uploading and sending PDFs without integration.
