Use cancellation for an activity with registrations

Open Events → Events → select your event → Activities and open the activity’s administration page.

An activity, a ticket type, and the whole event have different controls. Confirm which item you intend to cancel. Cancellation does not determine the institution’s refund policy.

Open the activity's administration page and use Cancel Activity when available. Deletion requires no non-incomplete tickets; cancellation is the distinct lifecycle action for a populated activity.

The cancellation check requires an active parent event and an activity that can transition to canceled. It rejects an activity whose end date is in the past or whose start is more than five days ago. For an activity without payments, use Basic Events Admin, Advanced Events Admin, Events Finance Admin, Events Superadmin, or Superadmin. For an activity with payments, use Events Finance Admin, Events Superadmin, or Superadmin. The person must have access to the event. If the action is unavailable, check dates/state as well as the assigned role; do not try to enable a separate cancellation or refund permission.

Refunds and communication

For a paid activity, the dialog offers cancellation with refunds or without refunds. A payment in an active dispute cannot be refunded; normal refund eligibility still applies. With refunds selected, a background job is queued; verify the individual refund results before reporting completion. Without refunds, individual registrations can be handled separately through their refund controls.

The cancellation dialog says registrants are not automatically notified merely because the activity is canceled. It separately says a refund generates refund notification. Plan any event-change communication with the organizer; do not assume the cancellation action sends an announcement.
