Custom Ticket Lookup

Feature similar to the existing User Lookup integration, but applied to individual tickets instead of users.

Proposed feature name:
Custom Ticket Lookup

Description
The Custom Ticket Lookup should allow the system to call an external URL when a ticket is opened, passing one or more ticket-related parameters (at least the Ticket ID, but could be useful also other fields like Category, Custom Fields, etc.).
The response returned by the external service (HTML or JSON) should be rendered directly in the right-side panel of the ticket view.

How it should work

• An administrator can configure a custom URL template, for example:

  https://external-system.local/ticket-lookup?ticketId=#TicketID#
  

• The system replaces placeholders with actual ticket values at runtime.
• The URL is called when the ticket is opened.
• The response returned by the endpoint is displayed in a dedicated right-side panel within the ticket UI, using the same rendering way already applied to User Lookup
• Optional authentication settings (Basic Auth) should be supported, similar to User Lookup.

Use cases

• Showing ERP / CRM / billing information related to the ticket
• Displaying SLA status or monitoring data
• Showing internal diagnostic or integration-specific data
• Enriching ticket context without navigating away from the ticket view
