How to track Webflow Form Submissions with google tag manager

To track Webflow form conversions in your analytics and advertising platform, you’ll need Google Tag Manager, and the Webflow form submits event listener javascript code.

Start by creating a custom HTML tag where you’ll paste the event listener code and fire it on pageview or DOM ready.

Create a custom event with the event name [formsubmit_event] 

the event happens only on successful submission of Webflow forms

Connect your marketing tags/pixel to this trigger, debug, test and publish once everything is okay.

To capture the form ID, create a dataLayer with the key [formID]

<script type="text/javascript">
$("form").submit(function(event) {
var formID = $(this).attr('id');
'event': 'formsubmit_event',
'formID': formID
