How this event is built in your container

GoHighLevel Calendar Booking is detected automatically. GoHighLevel's booking calendar widget is an iframe. This bridge listens for window messages from HighLevel-owned domains and matches a booking-confirmed payload.

This container includes a small Custom HTML tag, firing on All Pages, that listens for that native event and pushes dataLayer.push({ event: 'ghl_calendar_booking', ... }) itself - unlike this plugin's other events, there's no code for you to add manually.

For this to work, though:

• A native GoHighLevel calendar widget embedded on a page that has your GTM container snippet installed.

For reference, here is the exact script this container's bridge tag runs:

(function(){
  if (window.__gtmcbGhlCalendarBooking) { return; }
  window.__gtmcbGhlCalendarBooking = true;
  var trusted = ['leadconnectorhq.com','msgsndr.com','gohighlevel.com','highlevel.com','myfunnels.com'];
  var pattern = /(booking|appointment)[-_ ]?(confirmed|complete|completed|scheduled|success|booked)|(book|schedule)[-_ ]?(confirmed|complete|completed)/;
  var lastFired = 0;
  function isTrusted(origin) {
    try {
      var host = new URL(origin).hostname;
      return trusted.some(function (s) { return host === s || host.slice(-(s.length + 1)) === '.' + s; });
    } catch (e) { return false; }
  }
  function flatten(data) {
    if (typeof data === 'string') { return data; }
    try { return JSON.stringify(data); } catch (e) { return ''; }
  }
  window.addEventListener('message', function (event) {
    if (!isTrusted(event.origin)) { return; }
    var payload = event.data;
    var flat = flatten(payload).toLowerCase();
    if (!flat || !pattern.test(flat)) { return; }
    var now = Date.now();
    if (now - lastFired < 1500) { return; }
    lastFired = now;
    window.dataLayer = window.dataLayer || [];
    window.dataLayer.push({
      event: 'ghl_calendar_booking'
    });
  });
})();

The Microsoft Advertising (UET) tag itself is added automatically and wired to this trigger - you won't need to create or configure it by hand in GTM.

Troubleshooting

The event never fires.
Log window message events in the console while completing a test booking and compare the payload with the pattern in this bridge tag. If your calendar redirects to a confirmation page instead, use the Thank-You Page View event.

The event fires, but values show up blank or undefined.
Check that the pushed object's key names match exactly (case-sensitive) - a mismatched key like "Value" instead of "value" will show as undefined in GTM's variable preview.

GoHighLevel Calendar Booking fires twice for the same action.
You likely also have a manually-added Microsoft Advertising (UET) snippet listening for the same action alongside this container's own bridge tag. Remove the manual one, or disable it, before publishing.
