Currently the get a ticket by id endpoint will only return the ID and a few other system fields. The only way to return other ticket properties is to include the properties in the request URL using the &properties= parameter.
That said, while this may not be ideal, I do have one suggestion that I'd love to share with you. You may want to explore the option of using this endpoint here: Get all object properties where it'll return all the ticket properties. This will make things easier for you to grab the ticket properties and include it in the get a ticket by id endpoint.
