Ruby OAuth


This is a RubyGem for implementing both OAuth clients and servers in Ruby applications.

See the OAuth specs


sudo gem install oauth

The source code is now hosted on the OAuth GitHub Project

The basics

This is a ruby library which is intended to be used in creating Ruby Consumer and Service Provider applications. It is NOT a Rails plugin, but could easily be used for the foundation for such a Rails plugin.

As a matter of fact it has been pulled out from an OAuth Rails Plugin which now requires this GEM.

Demonstration of usage

We need to specify the oauth_callback url explicitly, otherwise it defaults to “oob” (Out of Band)

@callback_url = ""

Create a new consumer instance by passing it a configuration hash:

@consumer ="key","secret", :site => "https://agree2")

Start the process by requesting a token

@request_token = @consumer.get_request_token(:oauth_callback => @callback_url)
session[:request_token] = @request_token
redirect_to @request_token.authorize_url(:oauth_callback => @callback_url)

When user returns create an access_token

@access_token = @request_token.get_access_token
@photos = @access_token.get('/photos.xml')

Now that you have an access token, you can use Typhoeus to interact with the OAuth provider if you choose.

require 'oauth/request_proxy/typhoeus_request'
oauth_params = {:consumer => oauth_consumer, :token => access_token}
hydra =
req =, options) 
oauth_helper =, oauth_params.merge(:request_uri => uri))
req.headers.merge!({"Authorization" => oauth_helper.header}) # Signs the request
@response = req.response
