Yes I made it work by editing the hubspot form embed code. Here’s how one of mine looks now:
<!--[if lte IE 8]>
<script charset="utf-8" type="text/javascript" src="//js.hsforms.net/forms/v2-legacy.js"></script>
<![endif]-->
<script charset="utf-8" type="text/javascript" src="//js.hsforms.net/forms/v2.js"></script>
<script>
hbspt.forms.create({
css: '',
portalId: 'XXXXXX',
formId: '012aaa7e-03df-4c38-83fb-63474af1c182',
onFormSubmit: function($form) {
window.dataLayer = window.dataLayer || [];
window.dataLayer.push({
'event' : 'step 2',
'eventCategory' : 'lead',
'eventAction' : 'trial step 2'
});
}
});
</script>
In GTM I then created a trigger “custom event” with event name “step 2”. This is used as a firing trigger for a tag that does whatever the goal is (GA event, FB pixel conversion tag, etc)
