While I have no issue making a GET request to basecamp, I keep getting an
error every time I make a POST request.  The error is  

*RestClient::UnsupportedMediaType:* 415 Unsupported Media Type.  Does
anyone know why I might be getting this.  Below is the method I'm calling
for the POST request.

def create_bc_project(name, description)
  my_url = "https://basecamp.com/1942899/api/v1/projects.json"
  my_user = "<my user name>"
  my_password = "<my password>"

  resource = RestClient::Request.new(
              :method => :post,
              :url => my_url,
              :content_type => "application/json; charset=utf-8",
              :user_agent => "MyApp",
              :user => my_user,
              :password => my_password,
              :payload => { :name => name, :description => description }
            ).execute
end
