Social Media Authentication On Rails- Part 1

This Post is intended to provide an overview of the installation of social authentication plugins like Twitter/Github/Facebook & Google using Rails version 4 with devise(authentication plugin),omniauth(API Plugin for Social websites) & Mongo DB as underlying Database.


Before Proceeding towards installation/building a rails application that allows authentication with social websites we need to get API/Client Keys & API/Client Secret.


Here are the urls from where you can create an App and get the keys:


Facebook:

URL: Facebook Link

Twitter:>

URL: Twitter

Settings: Enter call back url as : http://127.0.0.1:3000/auth/twitter/callback/ under settings tab once you create an application

Google:

URL: Google URL

Settings: Go to API Access and enter redirect url as http://localhost:3000/users/auth/google_oauth2/callback



LinkedIn:>

URL: LinkedIn URL

Linked In Api Doesnot require any call back URI. Application URL is Enough for Linked in api as Omniauth-linked Has its method defined in Gem.

In the next post , the ROR code will be explained to integrate these social applications .
