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.
