The tracker automatically captures the following events without any site modification:
email_click, phone_click, form_submit.add_to_cart, remove_from_cart, view_cart, view_item, view_item_list, select_item, begin_checkout, add_shipping_info, add_payment_info, purchase, refund, generate_lead, sign_up, login, search, subscribe, contact, share.Meta Pixel and TikTok Pixel are not hooked directly. If those pixels are fired through GTM using the dataLayer event names above, the events are still counted here. Direct fbq() / ttq.track() calls without a dataLayer push are not captured.
