CRM
LeadLotus + HubSpot
Send lead attribution into every HubSpot contact.
HubSpot lets you create custom hidden form fields with your own internal name. LeadLotus matches against that name, so every form submission writes channel, drilldowns, landing page, and visit history straight onto the contact record — usable in lists, workflows, and reports.
How to set it up
HubSpot — Use hidden fields in forms1
Add the snippet to your site
Paste into your site's <head>. If you host a HubSpot CMS site, go to Settings → Website → Pages → Site header HTML and drop it there.
<!-- 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 the contact properties
In HubSpot: Settings (gear icon) → Properties → Create property. Object type: Contact. Create one single-line text property per field below — the Internal name must match exactly (e.g. "leadlotus-channel").
3
Add hidden fields in the form editor
Open the form (Marketing → Forms → Edit). Drag each property in from the left panel, click the field, and toggle "Make this field hidden". The internal name (which LeadLotus matches on) is already set from step 2.

4
Embed the form on your page
Use HubSpot's standard embed code. The LeadLotus snippet finds the rendered form, fills the hidden inputs, and HubSpot writes them onto the new contact on submit.
Attribution fields
LeadLotus writes these hidden field values just before your form submits.
