Overview

Send Request and get Response.

This service, in fact, works as an adapter for the RestClient gem. If you want to remove dependence on RestClient, you should rewrite Send class.

Instead of using these service directly, better use the request method Request#call. Which freeze request and define Request#sent_at timestamp.
