What is the call back url I should provide for spree social

I am using spree_social gem, for social media logins using facebook and google.

How ever while I am trying to create an app in twitter, they say call back url is invalid

http://localhost:3000/users/auth/twitter This is what I am giving as the call back url. What should I give the call back url to make it work

As it's mentioned in spree_social extension the callback url for

• Twitter, http://localhost:3000 (development) or http://your-site.com (production) (mentioned here).
• Facebook, no callback url required (see here).
• Google, http://localhost:3000/users/auth/google_oauth2/callback (development) or http://your-site.com/users/auth/google_oauth2/callback (production).
