LeadLotus + Typeform
Native Typeform attribution via hidden fields.
Typeform supports hidden fields natively. LeadLotus uses Typeform's documented data-tf-hidden attribute and URL-hash protocol so every response includes channel, source, and journey data — no Zapier needed.
Typeform integration uses the data-leadlotus-tf attribute on the embed wrapper.
How to set it up
Typeform — Use hidden fields1
Add the snippet to your site
Standard: paste into <head>. Snippet captures UTMs, referrer, and landing data on every page.
<!-- LeadLotus Attribution Snippet --> <script async src="https://www.leadlotus.com/snippet.js?key=YOUR_API_KEY" data-key="YOUR_API_KEY" data-endpoint="https://www.leadlotus.com/api/v1/ingest"> </script>
2
Create hidden fields inside your typeform
Open your typeform → Logic → "Personalize with data" → Hidden fields. Add hidden fields named exactly: leadlotus-channel, leadlotus-drilldown1, leadlotus-drilldown2, leadlotus-drilldown3, leadlotus-drilldown4, leadlotus-landing-url, leadlotus-first-visit, leadlotus-visits.
3
Tag the Typeform embed
Add the data-leadlotus-tf attribute to your embed container (or directly to the iframe). LeadLotus writes the data-tf-hidden attribute and splices the iframe URL hash so Typeform sees the values.
<div data-tf-widget="<your-id>" data-leadlotus-tf></div> <script src="//embed.typeform.com/next/embed.js"></script>
4
See attribution on every response
Hidden field values appear on each Typeform response and flow through any Typeform integration (Slack, HubSpot, Zapier, Google Sheets) — they're first-class fields, not metadata.
Attribution fields
LeadLotus writes these hidden field values just before your form submits.
