Get ticket link from given ticket number

Get ticket link from given ticket number

If I have a ticket number, let's say #8447, is there any way to create a usable link knowing only this and the URL of our Zoho Desk? Or is the only way to generate a link to the ticket by going into Zoho and searching that ticket number?

This question goes for both linking to the ticket internally, as well as creating a customer portal link. Are either of these possible?
