Monday.com’s WorkForms embed via an iframe with no GA4 or Google Tag Manager (GTM) support and no marketplace app that adds one. The post-submit Redirect URL setting shows a consent interstitial inside the iframe, so it is not useful for tracking.
Turns out the embed emits a message we can hang on for GA4 event tracking.
You can verify this yourself: open a page with an embedded monday.com form, paste this into the console, and submit a test entry:
window.addEventListener('message', e => console.log(e.origin, e.data));You should see output in the console that looks like this:
{ "source": "workforms", "type": "submit_success" }The message arrives on the parent page, so all the session data is available to send to a GA4 event.
Here’s how to set it up in Google Tag Manager (GTM):
GA4 / GTM tracking of Monday.com workform submissions
1. Add a listener (Custom HTML tag, fire on All Pages)
<script>
(function () {
var fired = false;
window.addEventListener('message', function (e) {
if (e.origin !== 'https://forms.monday.com') return;
var d = e.data;
if (d && d.source === 'workforms' && d.type === 'submit_success' && !fired) {
fired = true; // prevent dupes
window.dataLayer = window.dataLayer || [];
window.dataLayer.push({ event: 'monday_form_submit' });
}
});
})();
</script>2. Add a GTM Tag (GA4 Event)
- Google Analytics: GA4 Event
- Add your measurement ID
- Event Name: monday_form_fill (or whatever you want to name it)
- Add the trigger below
3. Add a GTM Trigger (Custom Event)
- Trigger Type: Custom Event
- Event name: monday_form_submit
- Fires on: All Custom Events
4. Verify and publish
GTM Preview → submit a test → both tags fire → check GA4 Realtime → publish.
