Cookieless lead tracking.

Attribute conversions to campaigns with a single ltclid URL parameter. No cookies, no fingerprinting — just a tiny script and a webhook.

1. Drop the tracker on client landing pages

<script src="https://leadtkr.com/tracker.js" async></script>

When visitors arrive at ?ltclid=abc123, the ID is saved to session storage and injected as a hidden field into every <form>.

2. POST conversions to the API

POST https://leadtkr.com/api/v1/conversion
Content-Type: application/json

{
  "ltclid": "abc123",
  "lead_name": "Jane Doe",
  "lead_email": "jane@example.com",
  "lead_phone": "+15551234567",
  "landing_page_url": "https://client.com/lp"
}

3. Review + export in the admin dashboard

Search logs by ltclid and export CSV for billing reconciliation.
