During booking, a referrer may collect the registrant's email or print them a handout. In both cases, the registrant is provided further information regarding your organization. This can all be customized to your needs.
Start by navigating to Settings in the top menu, and select a Calendar. From here, scroll to 'Edit Email & Handout Content'. This is where you can customize the content of reminders, emails, and handouts given to registrants.
Once completed, scroll further to 'Edit Email & Handout Behaviour'. This is where you can allow registrants to self-service appointments by including certain actions in the email.
