OmniAuth Meetup

OmniAuth::Strategies::Meetup is an OmniAuth strategy for authenticating to meetup.com with OAuth2. Read detailed information about the meetup.com implementation of OAuth2 here

Add to your Gemfile:

  gem 'omniauth-meetup'

Then bundle install.

To get started you will need to register an OAuth Consumer in your meetup.com account here

Here's a quick example, adding the middleware to a Rails app in config/initializers/omniauth.rb:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :meetup, ENV['MEETUP_KEY'], ENV['MEETUP_SECRET']
end

or with Devise

  config.omniauth :meetup, ENV['MEETUP_KEY'], ENV['MEETUP_SECRET'], callback_url: 'http://example.com/users/auth/meetup/callback'

Starting from version 1.4 in omniauth-oauth2 you must provide same callback url you have provided on API dashboard otherwise authentication won't work.

You can then implement your authentication as usual with OmniAuth as shown in the excellent Railscast 241

##Authentication Hash

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

   "refresh_token"=>"bcd234...", # This token can be used to refresh your access_token later
   "expires_at"=>1324720198,     # when the access token expires (Meetup tokens expire in 1 hour)
   "expires"=>true},
 "extra"=>
  {"raw_info"=>
