To create a tracker ticket, we use related_ticket_ids field in the payload. It automatically creates a tracker ticker & links the ticket ID mentioned in “related_ticket_ids”.
How to link the normal ticket to the existing Tracker ticket?
Update existing tracker ticker with additional ticket Id in related_ticket_ids field doesn’t link the ticket ID.
I see the API documentation also doesn’t specify the details of how to do this with update Ticket API. I’ve initiated a ticket with the Freshdesk support team for the same.
To link the normal ticket to the existing Tracker ticket, we would be able to make use of this PUT call to perform the action.
