You can track any forms created with HubSpot Forms with the usual method for tracking web forms with Insiteful (also included below, for your convenience). However, before you get started, please make sure to read about the important preliminary step in Hubspot Forms to ensure you’re able to track your web forms accurately Insiteful — nothing complicated, just an additional click!

Want to save lead data from users that start to fill out your HubSpot forms but don’t finish? It doesn’t have to be tedious. There’s nothing more disheartening than missing out on a potential opportunity due to form abandonment or website drop-offs; Insiteful can help you seal the leaks in your lead forms!

Before you get started with the how-to guide, make sure to complete the preliminary step below:

Troubleshooting HubSpot Forms  + Insiteful tracking (Important Pre-Requisite)

By default, HubSpot Forms renders forms in iFrames when embedded in an external website or page — unlike most all forms, which are simply HTML elements (ie. <form>, <input>, <select>…) added directly to your webpage. Browsers limit the information shared between iFrames (ie. your embedded HubSpot form) and parent frames (ie. your website), which is why it is so tricky to track HubSpot forms & fields.

Fortunately, Insiteful has pioneered a couple simple ways to track your existing HubSpot forms without changing much about how your website is set up:

First, our recommended approach — simply replace your current HubSpot form embed code with the special Insiteful + HubSpot Tracking code:

<script charset="utf-8" type="text/javascript" src="//"></script>
   portalId: "{{ YOUR HUBSPOT PORTAL ID }}",
   formId: "{{ YOUR HUBSPOT FORM ID }}",
   onFormReady: function($form){
      window.f = $form;
      $form.append('<script id ="insiteful_1" type="text/javascript">const getScript=(e,t)=>{var a=document.createElement("script"),n=document.getElementsByTagName("script")[0];a.async=1,a.onload=a.onreadystatechange=((e,n)=>{(n||!a.readyState||/loaded|complete/.test(a.readyState))&&(a.onload=a.onreadystatechange=null,a=void 0,n||t&&t())}),a.src=e,n.parentNode.insertBefore(a,n)}; getScript( "", function() { \
      insiteful_activate("{{ YOUR INSITEFUL ACTIVATION KEY }}"); }); \
      <' + '/' + 'script> ');
      $form[0].ownerDocument.defaultView.eval($form.find("script#insiteful_1").text()); // insiteful
      var win_hs = document.querySelector('.hbspt-form iframe').contentWindow;
      window.addEventListener('beforeunload', (event) => { win_hs.saveForm(); });
      window.addEventListener('unload', (event) => { win_hs.saveForm(); });
  onFormSubmit: function($form) {
      var win_hs = document.querySelector('.hbspt-form iframe').contentWindow;
      win_hs.in_fh = {}; win_hs.in_fe = {}; // insiteful

Important: be sure to replace the unique IDs bolded in blue above with the appropriate values from Hubspot & Insiteful, respectively. The unique ID for HubSpot forms can be retrieved from the ‘formId’ attribute in the embed code (or even the editor URL), as seen below, and the portal ID is just above it (read more here, via the HubSpot documentation). Meanwhile, the Insiteful activation key is available when login and navigate to the Install page.

Find your Hubspot Form's GUID

Alternatively, if you’d prefer to use the default Insiteful installation, simply check the “Set as raw HTML form” switch on in HubSpot (as seen below, official docs here), and the new embed code will not include an iFrame. This will remove the browser security restrictions mentioned earlier and allow Insiteful to track your HubSpot forms just like any other web form.

That said, choosing this option will remove the default HubSpot styling from your forms, so you may need to add some CSS to re-style them as desired, as seen below. Alternatively, you may be able to add the tracking code directly to your form in HubSpot (rather than via Google Tag Manager, which adds it to the entire website) if you’d like to track the form without changing the default iFrame-based implementation.

Read more about how-to do this from the official HubSpot documentation, here.
