ExternalReference – Znuny Ticket Operation for External System Integration

The ExternalReference add-on extends the Znuny GenericInterface with a specialized operation for ticket integration. It solves the common challenge where external systems (such as CRM or ERP solutions) need to perform actions on tickets but only know their own reference number rather than the internal Znuny TicketID.\n\nThe 'Ticket::ExternalReference' operation checks incoming requests to see if a ticket with the provided reference already exists in a defined dynamic field. If a match is found and the ticket is in a permitted state, it is updated. Otherwise, a new ticket is created, and the reference is stored for future updates. This significantly reduces complexity on the third-party system's side, as it no longer needs to maintain a mapping of Znuny-specific IDs.
