> ⚠️ Notice:
> This workflow uses the HTML to Docx node from customjs.space, which requires a self-hosted n8n instance and a CustomJS API key.

Landingpage → NDA Word Document (Docx) → Email Workflow

This workflow demonstrates how to:

1. Serve a landing page for requesting an NDA.
2. Receive form submissions from users.
3. Generate a Word Document (Docx) version of the NDA populated with the submitted data.
4. Send the completed NDA via email to a recipient.

• Includes success and error messages after submission.

• Submits data as JSON to the FormData Endpoint.

4. Respond to Webhook

• Node: Respond to Webhook
• Returns the landing page HTML to the visitor when accessing the landing page URL.

5. FormData Endpoint

• Node: FormData Endpoint (Webhook)
• Receives the submitted form data from the landing page.
• Passes data to the NDA (HTML Version) node.

8. Send Email

• Node: Send email

• Sends the generated NDA Docx as an email attachment.

• Email configuration:

Notes

• Sticky Notes provide internal documentation and guidance for the workflow:

  • Sticky Note1 – Landingpage server info
  • Sticky Note – FormData endpoint info

• Dynamic Form Submission: The form posts JSON to the FormData Endpoint.

• Automation Flow: Landingpage → Form Submission → NDA HTML → Docx → Email

Requirements

• Self-hosted n8n instance
• CustomJS API key
• SMTP credentials
• Optional: Tailwind CSS CDN for landing page styling

Customization Tips

• Landing Page Styling: Adjust the HTML for Landingpage node for branding, colors, or additional fields.

• Email Settings: Change Send email node to modify sender, recipient, or message content.
• Field Mapping: Ensure all form input names match the NDA template placeholders.
