The PUT method is idempotent meaning multiple identical requests have the same effect as a single request and is used to update or fully replace a resource at a given URI. POST is generally used to create new resources and is not idempotent, since repeated calls can create multiple resources. GET is used only to retrieve data. DELETE removes a resource, and options describes the communication options available for a resource.
