How to link to ticket details by ticket number?

Hi,

In short: how can I link to an osTicket ticket details page with an url that has the ticket number (not ID) as input?

Explanation: I'm in the process of linking several of our systems (Gitweb, Gerrit, Bugzilla and osTicket) together. All of them have the option to automatically change a string "bug 123" into, for example, a hyperlink to our bugzilla database. I also would like to do that for osTicket tickets. So, I want to replace the string "Ticket #123456" to a url that links directly to the ticket details page. But I don't have the ticket ID, just the ticket number, so I cannot use the standard ticket details url.

Assume the person clicking the url is already logged in, so authentication is not a problem.

Thanks a lot,

Roel
