You must make an HTTP call to send an email and receive a response

Question

I am writing a Sinatra application that will send an email using SendGrid. They provide a REST API for sending emails, and I would like to find a better way to make a call to this API and get a response.

Call format:

https://sendgrid.com/api/mail.send.xml?api_user=[e-mail]&api_key=secureSecret&to=[e-mail]&toname=Destination&subject=Example%20Subject&text=testingtextbody&from=[e-mail]

An XML response that I need to parse to verify success / failure. Additional information at http://sendgrid.com/documentation/ApiWebMail

What is the best way to make a call and parse the result?

uri = Addressable::URI.parse(url)
uri.query_values # => {"api_user"=>"[e-mail]", "api_key"=>"secureSecret", "to"=>"[e-mail]", "toname"=>"Destination", "subject"=>"Example Subject", "text"=>"testingtextbody", "from"=>"[e-mail]"}

, , uri.query_values=.
