Auth0 - Ruby

Ruby API client for the Auth0 platform.

This gem can be installed directly:

$ gem install auth0

... or with Bundler:

bundle add auth0

You can build the API documentation with the following:

bundle exec rake documentation

To view the generated documentation, open doc/Auth0/Api.html .

This SDK provides access to the Management API v2 via modules that help create clear and accurate calls. Most of the interaction is done through the Auth0Client class, instantiated with the required credentials.

As a simple example of how to get started, we'll create an admin route to point to a list of all users from Auth0:

# config/routes.rb
Rails.application.routes.draw do
  # ...
  get 'admin/users', to: 'all_users#index'
  # ...
end

... and a Controller to handle that route:

# app/controllers/all_users_controllers.rb
require 'auth0'

class AllUsersController < ApplicationController
  # Get all users from Auth0 with "auth0" in their email.
  def index
    @params = {
      q: "email:*auth0*",
      fields: 'email,user_id,name',
      include_fields: true,
      page: 0,
      per_page: 50
    }
    @users = auth0_client.users @params
  end
	
  private
	
  # Setup the Auth0 API connection.
  def auth0_client
    @auth0_client ||= Auth0Client.new(
      client_id: ENV['AUTH0_RUBY_CLIENT_ID'],
      token: ENV['AUTH0_RUBY_API_TOKEN'],
      domain: ENV['AUTH0_RUBY_DOMAIN'],
      api_version: 2,
      timeout: 15 # optional, defaults to 10
    )
  end
end

In this example, we're using environment variables to store the values needed to connect to Auth0 and authorize. The token used above is an API token for the Management API with the scopes required to perform a specific action (in this case read:users). These tokens can be generated manually using a test Application or with the Application being used for your project.

Finally, we'll add a view to display the results:

# app/views/all_users/index.html.erb
<h1>Users</h1>
<%= debug @params %>
<%= debug @users %>

This should show the parameters passed to the users method and a list of users that matched the query (or an empty array if none).

In addition to the Management API, this SDK also provides access to Authentication API endpoints with the Auth0::API::AuthenticationEndpoints module. For basic login capability, we suggest using our OmniAuth stategy detailed here. Other authentication tasks currently supported are:

• Register a new user with a database connection using the signup method.
• Redirect a user to the universal login page for authentication using the authorization_url method.
• Log a user into a highly trusted app with the Resource Owner Password grant using the login method.
• Exchange an authorization code for an access token on callback using the obtain_user_tokens method (see the note on state validation below).
• Send a change password email to a database connection user using the change_password method.
• Log a user out of Auth0 with the logout_url method.

Important note on state validation: If you choose to implement a login flow callback yourself, it is important to generate and store a state value, pass that value to Auth0 in the authorization_url method, and validate it in your callback URL before calling obtain_user_tokens. For more information on state validation, please see our documentation.

Please note that this module implements endpoints that might be deprecated for newer tenants. If you have any questions about how and when the endpoints should be used, consult the documentation or ask in our Community forums.

Auth0 helps you to:

• Add authentication with multiple authentication sources, either social like Google, Facebook, Microsoft Account, LinkedIn, GitHub, Twitter, Box, Salesforce among others, or enterprise identity systems like Windows Azure AD, Google Apps, Active Directory, ADFS or any SAML Identity Provider.
• Add authentication through more traditional username/password databases.
• Add support for linking different user accounts with the same user.
• Support for generating signed JSON Web Tokens to call your APIs and flow the user identity securely.
• Analytics of how, when, and where users are logging in.
• Pull data from other sources and add it to the user profile with JavaScript rules.

1. Go to Auth0 and click Sign Up.
2. Use Google, GitHub or Microsoft Account to login.
