Exposing services in RESTful web service

Question

I am creating a web service and I follow the RESTful way of doing it. So I have resources such as Person, Ticket etc. I have all the normal CRUD operations, some finders and so on. I also want to expose service methods such as randomTicket() which is defined in a RandomTicketGenerator class. I am unsure if it is bad to expose service methods in a REST API like this? For instance the path above would be /randomTicket and only answer on GET requests.

Answer 1

/ticket/random is a bit confusing as it could be interpreted as meaning 'give me the ticket with ID=random'

How about returning a single item via: GET /ticket?random=true

Or a list of items via: GET /tickets?random=true&maxItems=1
