groundhogg/step/email/confirmed
This action is very useful in some cases for the Groundhogg developer. This action runs when the user confirms the email address by clicking on the confirmation link.
do_action('groundhogg/step/email/confirmed', $contact->get_id(), Preferences::CONFIRMED, Preferences::CONFIRMED, $event->get_funnel_id() );
When a user uses this action user will get contact id, status and funnel ID of contact.
