Zendesk ticket matching across service desks

When replies land in the wrong ticket

Our customer faced a common but time-consuming challenge: two different service desk systems needed to exchange information regularly.
The issue: the external service desk didn’t reply to the original Zendesk emails but sent a new message for each response, including the ticket number in the subject. Without special handling, Zendesk couldn’t automatically assign these emails to the correct case and kept creating new tickets instead.

The starting point: communication gaps in service

• Incoming emails could not be automatically mapped to the original ticket.

• Manually merging tickets consumed time and resources.

• Keeping the full conversation in a single ticket thread was barely possible.

Our approach: automated ticket matching

To simplify and automate communication, we designed the following process:

Automatic duplication of the ticket number
When a ticket is created, the Zendesk ticket ID is automatically copied to a dedicated ticket field.

Using the Knots Ticket Parser app
New emails are scanned by Ticket Parser Extract Patterns (by Knots) to detect the matching ticket number in the subject.

Sender address check
In addition to the ticket number, the sender’s email address is verified.

Automatic merge
If both the ticket number and sender match, the new email is merged into the existing ticket.

Result

You keep the complete conversation in a single ticket — even when the external service desk starts new emails. This reduces manual merges, prevents loss of context, and speeds up resolution — without any changes to the external system.

Day-to-day impact
You don’t need to modify the external system and still benefit from a clean conversation history in Zendesk — fewer follow-ups, less context hunting, faster closure.

At a glance

• Time savings: No more manual merges.

• Clarity: All communication in one ticket thread.

• Efficiency: Faster handling with fewer steps.

• Quality: Fewer assignment errors.
