The Registrations for the Events Calendar plugin fires a JavaScript event after a successful registration. You can use this event in your JavaScript code to track conversions using Google Analytics.
You can use this code as a guide to how you can set up your tracking. You can add it to the “Custom JavaScript” area found on the “Form” tab inside the Registrations settings page.
jQuery(window).on('rtecsubmissionajax', function (event) {
var eventID = event.el.attr('data-event'), // Event post ID
eventTitle = jQuery('.tribe-events-single').find('.tribe-events-single-event-title').length ? jQuery('.tribe-events-single').find('.tribe-events-single-event-title').text() : jQuery('h1').first().text(); // Title of event or title of page
ga('send', {
hitType: 'event',
eventCategory: 'Registration',
eventAction: 'submit',
eventLabel: eventID + ' - ' + eventTitle
});
});
