    }
}

Devise

First define your application id and secret in "config/initializers/devise.rb" your scope maybe different. TODO add all available scopes.

config.omniauth :practicefusion, ENV['PF_APP_ID'], ENV['PF_APP_SECRET'], {
                                                                                      scope: 'user:r_basic',
                                                                                      response_type: 'code'
                                                                                  }

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

devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }

f Devise default callback URL is '/users/auth/practicefusion/callback' with the above route.

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

devise :omniauthable, :omniauth_providers => [:practicefusion]

Then make sure your callbacks controller is setup.

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def practicefusion
        @user = User.find_for_practicefusion(request.env['omniauth.auth'], current_user)

        if @user.persisted?
          sign_in_and_redirect @user, event: :authentication
        else
          redirect_to new_user_registration_url
        end     
  end
end

and bind to or create the user

def self.find_for_practicefusion(access_token, signed_in_resource = nil)
    user = User.where(ehr_user_guid: access_token['uid']).first
      unless user
        user = User.create(name: access_token['info']['first_name'] + ' ' + access_token['info']['last_name'], ehr_user_guid: access_token['uid'], email: access_token['info']['email'], password: Devise.friendly_token[0,20])
      end
    user
end
