Send, track, and manage legally binding e-signatures from your own app, CRM, or automation. REST API with real-time webhooks. $0.10/request or included with Team.
Your app sends API request
VisiSign delivers to signer
Signer signs on any device
Webhook fires to your system
Signed PDF stored with audit trail
webhook: envelope.completed
200 OKWhy embedded
Not in a separate portal. Not behind a login wall. Not as an afterthought.
Context switching kills conversion
Every time you redirect a signer to an external portal, you lose momentum. Embedded signing keeps the experience inside your app or workflow.
Standalone signing portals break automation
If your signing tool is not in your stack, every workflow needs manual handoffs. API-first signing removes the gap between "agreement generated" and "agreement signed."
API gating is the wrong model
Most platforms lock API access behind enterprise tiers. VisiSign gives you API access from day one. $0.10/request with no monthly fee, or included with Team.
Signing inside your app
Signing happens inline. No redirects, no external portals, no broken flow.
Signing is embedded directly in your application. Your users never leave your product.
Send a signature request
No SDK required. No complex setup. Standard REST with JSON payloads.
# Send a document for signing
curl -X POST https://api.visisign.app/v1/signature_requests \
-H "Authorization: Bearer vsk_your_api_key" \
-H "Content-Type: application/json" \
-d '{
"title": "Service Agreement",
"signers": [{
"name": "Jane Smith",
"email": "jane@example.com"
}]
}' Response
REST API
Standard HTTP. JSON in, JSON out. No SDK required.
Templates
Define a document once, send with dynamic data via API.
Signed PDF download
Retrieve the signed document and signing certificate programmatically.
Implementation time
No procurement cycle. No onboarding calls. Just code.
~15 min
First signature request
Create an account, get an API key, send a test signature request from cURL or your app.
~1 hour
Webhook-integrated flow
Send signature requests, listen for completion webhooks, and update your database or CRM automatically.
~half day
Production workflow
Templates, sequential signing, error handling, signed PDF storage, and end-to-end testing.
Use cases
Signing becomes a step in your workflow, not a separate tool your team logs into.
New customer signs up, your app sends a service agreement automatically. They sign without leaving your product. Webhook confirms completion and you provision their account.
Deal closes in your CRM, contract fires via API. The signed PDF attaches back to the deal record. No manual upload. No context switch.
Offer letters, NDAs, and policy acknowledgments sent automatically when a new hire is created. Sequential signing routes documents through the right people.
Vendor agreements and contractor SOWs sent in bulk from templates. Track status via dashboard or webhooks. Download signed copies programmatically.
Waivers, delivery confirmations, and field approvals signed on any device. SMS delivery gets signatures from people who never check email.
AI systems that generate contracts, proposals, or agreements can send them for signature via API. The signing step becomes part of the automated pipeline.
Real-time events
Your system knows what happened the moment it happens. No polling. No checking back.
