REST API v2

Build with Verasign API

Integrate electronic signatures into your application with our powerful, developer-friendly API. Full documentation and SDKs for popular languages.

Create, upload, and manage documents programmatically. Support for PDF, DOCX, and more.

const doc = await verasign.documents.create({
  file: uploadedFile,
  name: "Contract.pdf"
});

Send signature requests to multiple recipients with custom fields and deadlines.

const request = await verasign.signatures.create({
  documentId: doc.id,
  signers: [{ email: "signer@example.com" }]
});

Get real-time notifications when documents are viewed, signed, or completed.

// POST /webhooks
{
  "event": "document.signed",
  "data": { "documentId": "doc_123" }
}

Create and use templates for frequently used document types.

const contract = await verasign.templates.use({
  templateId: "tmpl_nda",
  variables: { clientName: "Acme Inc" }
});
