Given order cancelling as a requirement, what is the best design option of representing this operation in RESTful way and why? I can think at least of the following PUT /orders/{id}/cancelled (with an empty body) PUT /orders/{id} (with an entire order JSON/XML/etc with changed attribute cancelled )
