GET defines a reading access of the resource without side-effects. The resource is never changed via a GET request, e.g., the request has no side effects (idempotent).

PUT creates a new resource. It must also be idempotent.

DELETE removes the resources. The operations are idempotent. They can get repeated without leading to different results.
