Integrations

Works with everything you already use.

No new CRM. No new form tool. Just attribution that finally tells you what’s working.

One line of code on your website. No per-platform setup. Whether you use HubSpot, Salesforce, native WordPress forms, or no CRM at all, Lead Source captures every lead with full source attribution.

One snippet. Every form on your site.

The Lead Source script goes once in the <head> of your website. Five minutes total. From that moment on, every form on every page is automatically tracked.

No per-form config. No per-platform setup. No integration project. We work alongside your existing CRM, form tool, website builder. Or no CRM at all.

Don’t see your tool? It probably still works.

Lead Source works at the website level, not the form-tool level. If your form lives on a website you can add a <script> tag to, we can track it. That covers almost every form on the internet.

For custom CRMs, custom databases, or non-standard form setups. We have a webhook endpoint. Send us a question.
