OmniAuth WildApricot OAuth2 Strategy

Strategy to authenticate with WildApricot via OAuth2 in OmniAuth.

For more details, read the WildApricot docs: https://gethelp.wildapricot.com/en/articles/200-single-sign-on-service-sso

Installation

First start by adding this gem and its dependencies to your Gemfile:

gem 'omniauth', '~> 2.0'
gem "omniauth-rails_csrf_protection"
gem 'omniauth-wild-apricot'

If you need to use the latest HEAD version, you can do so with:

gem 'omniauth-wild-apricot', github: 'rocket-house/omniauth-wild-apricot'

Then bundle install.

WildApricot API Setup

Go to 'https://myWAsite.com/admin/apps/integration/authorized-applications/' then:

Select 'Authorize Application', then select 'Server Application'
Name your application
Select desired permission level: read/write
Click 'Generate client secret'
Select 'Authorize users via Wild Apricot single sign-on service'
Fill in your app's redirect domain
Take note of the following information:
- Client ID
- Client Secret

Additionally, you'll need your Wild Apricot Account # which can be found on the admin/billing page. You also need your site's url. If you're billing page is 'https://myWAsite.com/admin/billing/' then your site url is 'https://myWAsite.com/'.

The above information can be placed into your project's .env file (see examples/.env-example), or set as environment variables in your hosting provider's application settings.

Usage using OmniAuth

Here's an example for adding the middleware to a Rails app in config/initializers/omniauth.rb. In this example, we are storing the key variables in the project's .env file (see examples/.env-example).

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :wild_apricot, ENV['WA_CLIENT_ID'], ENV['WA_CLIENT_SECRET'],
    {
      account_num: ENV['WA_ACCT_NUM'], # found at: https://myWAsite.com/admin/billing/
      site_url: ENV['WA_SITE_URL'],    # set to: 'https://myWAsite.com/'
      callback_path: '/callback/wild_apricot' # must match your session controller route
    }
end

You'll need some routes to handle the callback, and a session controller:

Rails.application.routes.draw do
  ...

  # Routes for OmniAuth
  # Wild Apricot uses GET route; use POST for other providers
  # post '/auth/:provider/callback', to: 'sessions#create'
  get '/callback/:provider', to: 'sessions#create'
  get '/logout', to: 'sessions#destroy', as: :logout

end

For your views you can login using:

<%# omniauth-wild-apricot 0.1.x uses OmniAuth 2 and requires using HTTP Post to initiate authentication: %>
<%= link_to "Sign in with Wild Apricot", '/auth/wild_apricot', method: :post %>

<%# when using rails 7.0+ with turbo-links, you'll need to bypass turbo; you *must* use botton_to %>
<%= button_to "Sign in with Wild Apricot", '/auth/wild_apricot', method: :post, 'data-turbo': false %>

Note: the route /auth/wild_apricot comes included with omniauth (/auth/:provider)

Usage using Devise

If you are using Devise then it will look like this:

Devise.setup do |config|
  # other stuff...

  config.omniauth :wild_apricot, ENV['WA_CLIENT_ID'], ENV['WA_CLIENT_SECRET'],
    {
      account_num: ENV['WA_ACCT_NUM'], # found at: https://myWAsite.com/admin/billing/
      site_url: ENV['WA_SITE_URL']     # set to: 'https://myWAsite.com/'
    }

  # other stuff...
end

NOTE: If you are using this gem with devise with above snippet in config/initializers/devise.rb then do not create config/initializers/omniauth.rb which will conflict with devise configurations.

Then add the following to 'config/routes.rb' so the callback routes are defined.

devise_for :users, controllers: { omniauth_callbacks: 'users/omniauth_callbacks' }

Make sure your model is omniauthable. Generally this is "/app/models/user.rb"

devise :omniauthable, omniauth_providers: [:wild_apricot]

Then make sure your callbacks controller is setup.

# app/controllers/users/omniauth_callbacks_controller.rb:

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def wild_apricot
      # You need to implement the method below in your model (e.g. app/models/user.rb)
      @user = User.from_omniauth(request.env['omniauth.auth'])

      if @user.persisted?
        flash[:notice] = I18n.t 'devise.omniauth_callbacks.success', kind: 'Wild Apricot'
        sign_in_and_redirect @user, event: :authentication
      else
        session['devise.wild_apricot_data'] = request.env['omniauth.auth'].except('extra') # Removing extra as it can overflow some session stores
        redirect_to new_user_registration_url, alert: @user.errors.full_messages.join("\n")
      end
  end
end

and bind to or create the user

def self.from_omniauth(access_token)
    data = access_token.info
    user = User.where(email: data['email']).first

    # Uncomment the section below if you want users to be created if they don't exist
    # unless user
    #     user = User.create(name: data['name'],
    #        email: data['email'],
    #        password: Devise.friendly_token[0,20]
    #     )
    # end
    user
end

For your views you can login using:

<%# omniauth-wild-apricot 0.1.x uses OmniAuth 2 and requires using HTTP Post to initiate authentication: %>
<%= link_to "Sign in with Wild Apricot", '/auth/wild_apricot', method: :post %>

<%# when using rails 7.0+ with turbo-links, you'll need to bypass turbo; you *must* use botton_to %>
<%= button_to "Sign in with Wild Apricot", '/auth/wild_apricot', method: :post, 'data-turbo': false %>

Auth Hash

Here's an example of an authentication hash available in the callback by accessing request.env['omniauth.auth']:

{
  "provider":"wild_apricot",
  "uid":"50152421",
  "info":{
    "email":"anita.borg@example.com",
    "first_name":"Anita",
    "last_name":"Borg",
    "name":"Anita Borg"
  },
  "credentials":{
    "token":"thaXd6xjo4qpQnwraebbGA40vzg-",
    "refresh_token":"rt_2023-09-02_VguuDxHFznplhQk1YaOtNrxcgyk-",
    "expires_at":1693689961,
    "expires":true
  },
  "extra":{
    "raw_info":{
      "AdministrativeRoleTypes":["AccountAdministrator"],
      "FirstName":"Anita",
      "LastName":"Anita",
      "Email":"anita.borg@example.com",
      "DisplayName":"Anita, Anita",
      "PasswordExpiration":"2024-08-17T05:42:03+00:00",
      "MembershipLevel":{
        "Id":1253690,
        "Url":"https://api.wildapricot.org/v2/accounts/321456/MembershipLevels/1253690",
        "Name":"FREE"
      },
      "Status":"Active",
      "Id":50152421,
      "Url":"https://api.wildapricot.org/v2/accounts/321456/Contacts/50152421",
      "IsAccountAdministrator":true,
      "TermsOfUseAccepted":true
    }
  }
}

Fixing Protocol Mismatch for `redirect_uri` in Rails

Just set the full_host in OmniAuth based on the Rails.env.

# config/initializers/omniauth.rb
OmniAuth.config.full_host = Rails.env.production? ? 'https://domain.com' : 'http://localhost:3000'
