RT has many interfaces for creating and updating tickets. A web interface is available for both logged in users and guest users. It is easily tailored by granting or denying specific permissions to users as well as by adding custom fields and data to tickets. Template callbacks allow the modification of the software’s web pages without requiring extensive knowledge.

Email is another primary interface to RT and is often the only interface many guest users see. The email system includes support for auto-responses, attachments, and full customization of the rules which govern to whom and when email is sent. Emails are stored in RT as correspondence on a ticket, and the software can make a distinction between public replies and private comments to show them as appropriate.

A full REST API and a command-line tool are also provided as another way to interact with RT.
