Lead capture forms
Lead capture is an embeddable sign-up form. Drop one line of code on your site and submissions arrive as Karani contacts, automatically tagged Web signup.
Configure it at karani.co/contacts/lead-capture, or via Lead Capture on the contacts list.

Embedding it
Section titled “Embedding it”Copy the snippet and paste it into your page:
<script src="https://karani.co/embed/YOUR-KEY.js" async></script>The form appears where the script tag sits.
Placing it somewhere specific
Section titled “Placing it somewhere specific”To control where it lands, add a target element anywhere on the page:
<div data-karani-embed="YOUR-KEY"></div>The iframe drops into that element instead of next to the script tag. Useful when your script tags live in the page footer.

What happens on submission
