OmniAuth Mailup

MailUp OAuth2 Strategy for OmniAuth 1.0.

Add the strategy to your Gemfile:

gem 'omniauth-mailup'

Then bundle install.

OmniAuth::Strategies::MailUp is simply a Rack middleware. Read the OmniAuth 1.0 docs for detailed instructions: https://github.com/intridea/omniauth.

use OmniAuth::Builder do
  provider :mailup, ENV['MAILUP_CLIENT_ID'], ENV['MAILUP_CLIENT_SECRET']
end

In Rails, you'll want to add to the middleware stack (config/initializers/omniauth.rb):

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :mailup, ENV['MAILUP_CLIENT_ID'], ENV['MAILUP_CLIENT_SECRET']
end

Here's an example Authentication Hash available in request.env['omniauth.auth']:

{
  provider: 'mailup',
  uid: '10',
  info: {
    company: 'ACME, Inc.',
    nickname: 'm12345',
    is_trial: true,
    version: "8.4"
  },
  credentials: {
    token: 'adsf456lkj758klfdsg5634kl',        # OAuth 2.0 access_token.
    refresh_token: '6l5k37hl345656lh342345lh', # OAuth 2.0 refresh_token.
    expires: true,
    expires_at: 1369866442
  }
}

An example Sinatra app is provided in example/config.ru. Simply follow these instructions:

cd example
bundle
rackup config.ru

You can then view the app in your browser at localhost:9292.

Please note that in order to authenticate with MailUp you will need to tunnel your local app using a service like PageKite (recommended) or Localtunnel.
