Components

• Resource Path

Resource path is the “request target” or the desired destination for the object. For example, a resource path could be “codermerlin.com/wiki/database/grades” where the object would be sent to the grades directory of the host.

• HTTP Verb

With an HTTP Verb, the actions of the resource could be easily defined. A handy acronym to remember the available HTTP Verbs is “C R U D” or Creation (creates a resource), Retrieval (retrieves a resource), Update (updates a resource), and Deletion (deletes a resource).

• Body

The body is the contents of the resource, and conveniently uses the JSON (JavaScript Object Notation) as the format. Both Creation operations and Update operations contain a body, but a Retrieval operation does not contain a body. In addition, the Deletion operation would also not contain a body.

• Header

A header in short is simply a description of the resource, essentially acting as a metadata for the resource.
