Triggers define how and when a flow starts in RapidPro.app, letting you launch the right automation based on events such as a keyword message, an unmatched message, a scheduled date/time, a missed call, a new conversation, a Facebook referral, a ticket closing, or Facebook opt-in/opt-out events.

A Ticket Closed trigger automatically starts a flow for a contact when an agent closes their ticket, which is useful for follow-ups and “handoff cleanup” actions like removing groups/labels or restoring normal automation—often best handled with a Background Flow to avoid interrupting any active messaging flows.
