The HTTP Verbs
POST
We can think of POST as a way to create new resources.
Creating
Typically the resources that are created are subordinate resources; that we POST to the parent and the service associates the new resource to the parent.
On Success
We should expect a HTTP status of 201 to be returned, including a link to the newly created resource.
