# OAuth

You can configure authentication services with external OAuth providers, right now Twitter, Facebook, Google and Wordpress are supported.

## 1. Create an App on the platform

For each platform, go to their developers section and follow their guides to create an app.

## 2. Set the authentication URL of your Consul Democracy installation

They'll ask you for the authentication URL of your Consul Democracy installation, and as you can see running `rails routes | grep omniauth` at your Consul Democracy repo locally:

```bash
user_twitter_omniauth_authorize GET|POST /users/auth/twitter(.:format) users/omniauth_callbacks#passthru
user_twitter_omniauth_callback GET|POST /users/auth/twitter/callback(.:format) users/omniauth_callbacks#twitter
user_facebook_omniauth_authorize GET|POST /users/auth/facebook(.:format) users/omniauth_callbacks#passthru
user_facebook_omniauth_callback GET|POST /users/auth/facebook/callback(.:format) users/omniauth_callbacks#facebook
user_google_oauth2_omniauth_authorize GET|POST /users/auth/google_oauth2(.:format) users/omniauth_callbacks#passthru
user_google_oauth2_omniauth_callback GET|POST /users/auth/google_oauth2/callback(.:format) users/omniauth_callbacks#google_oauth2
user_wordpress_oauth2_omniauth_authorize GET|POST /users/auth/wordpress_oauth2(.:format) users/omniauth_callbacks#passthru
user_wordpress_oauth2_omniauth_callback GET|POST /users/auth/wordpress_oauth2/callback(.:format) users/omniauth_callbacks#wordpress_oauth2
```

So for example the URL for Facebook application would be `yourdomain.com/users/auth/facebook/callback`.

## 3. Set the key and secret values

When you complete the application registration you'll get a *key* and *secret* values, those need to be stored at your `config/secrets.yml` file:

```yml
  twitter_key: ""
  twitter_secret: ""
  facebook_key: ""
  facebook_secret: ""
  google_oauth2_key: ""
  google_oauth2_secret: ""
  wordpress_oauth2_key: ""
  wordpress_oauth2_secret: ""
  wordpress_oauth2_site: ""
```
