How to Sign an NDA Online

Non-Disclosure Agreements are the most common business contract. Here's how to sign one electronically — without printing, scanning, or meeting in person.

Steps

  1. 1

    Write or paste your NDA terms (or use markdown)

  2. 2

    Enter both parties' names and email addresses

  3. 3

    Send via API or MCP — recipient gets a signing link by email

  4. 4

    Both parties sign with an animated handwriting signature

  5. 5

    Signed PDF with SHA-256 certificate delivered to both inboxes

Try it with curl

curl
curl -X POST https://signb.ee/api/send \
  -H "Content-Type: application/json" \
  -d '{
    "content": "# Your Document\n\nContent here...",
    "senderName": "Your Name",
    "senderEmail": "you@email.com",
    "recipientName": "Recipient",
    "recipientEmail": "recipient@email.com"
  }'

Legal validity

Electronic signatures are legally binding under the ESIGN Act (US), eIDAS Regulation (EU), and Electronic Communications Act (UK). Every Signbee document includes a SHA-256 tamper-proof certificate.

More details

Most NDA signing tools require creating an account, uploading a template, and configuring fields. With Signbee, you skip all of that — write your NDA terms as markdown, specify the parties, and send. The recipient gets a signing link that works on any device.

Your signed NDA includes a SHA-256 certificate page with timestamps, IP addresses, and verification methods for both parties. This provides stronger legal evidence than a scanned wet signature, which proves nothing about when or how it was applied.

Signbee supports both mutual (two-way) and one-way NDAs. The document content is entirely up to you — write it as markdown text or pass a PDF URL if you have one from your legal team.

For automated NDA workflows, use the API to trigger signing from your CRM or onboarding flow. When a new client is added to your system, automatically generate and send an NDA for signature.
