Google Tag Manager

Freeform includes built-in support for Google Tag Manager (GTM) if you wish to use that with your forms. This guide assumes you are familiar with GTM. We cannot provide any assistance with setting this up, aside from the basics.

​Setup Instructions

1

​Enable Google Tag Manager inside Freeform

  • Go to the 'Single' integration section in Freeform Settings (Freeform → Settings → Integrations → Single).
  • Click on Google Tag Manager in the list.
  • Enable it by toggling on the Enabled setting.
  • If you'd like GTM to be enabled for all forms by default, toggle on the Enabled by default setting.
  • If you wish to have Freeform insert its own scripts, enter your GTM ID (GTM-XXXXXX) in the Container ID setting and a custom event name (if applicable) in the Event Name setting.
  • Save the form.

​Configure the Form

To use this integration on your form(s), you'll need to configure each form individually. If you toggled on the Enabled by default setting in the Freeform Settings, it will automatically be ON for all forms. You can disable them for each form as necessary.

  • Visit the form inside the form builder.
  • Click on the Integrations tab.
  • Click on Google Tag Manager in the list of available integrations.
  • On the right side of the page:
    • Enable (or disable) the integration.
    • Adjust any of the settings as needed.
  • Save the form.

​Customizing

To customize what gets sent to the events, you can write your own JS and add an event listener in your template, like this:

window.addEventListener('freeform-gtm-data-layer-push', function (event) {
  event.payload.myCustomValue = 'something_here';
  event.payload.otherCustomValue = 'other_value';
});

This would then attach whatever you add to the payload to the event that is being pushed to GTM.

​Submit a Test Submission

  • Visit your form on your site.
  • Fill out the form and submit it.
  • The data should have been pushed to GTM using the specified event name.

The success of this is not observable on your site, as this event goes to GTM via some sockets, so there's nothing in the network tab.

​Troubleshooting

Google offers a Tag Assistant tool along with a Tag Assistant Companion Chrome extension. These help troubleshoot installation of gtag.js and Google Tag Manager. When the Chrome extension is present, it enables additional features for Tag Assistant including debugging iframes and debugging multiple windows from the same debug session.
