By default, no attendee confirmation or organizer notification emails are sent when a new RSVP attendee is created via the API. If this parameter is set to active then when a new RSVP attendee is created via the API:
- an attendee confirmation email is sent to the RSVP attendee's email address if confirmation emails are enabled for the event
- an internal organizer notification email is sent to to the organizer notification email addresses listed under RSVP settings(
notify_emails) if notify_frequency is set to all for an event.
Note that attendee reminder and follow-up emails are not affected by this setting.
