A keyword trigger starts a flow automatically when the first word of an incoming message matches one or more keywords you define (for example, starting a registration flow when a contact sends “JOIN”), with options to control matching behavior and optionally restrict the trigger by channel and/or contact groups.
Customer Service: Triggering a Follow-Up Flow After a Ticket is Closed
