Getting Started

Add the gem to your Gemfile:

gem 'oauth2'

Basic Setup

Configure your OAuth provider:

OAuth2.configure do |config|
  config.client_id = ENV['OAUTH_CLIENT_ID']
  config.client_secret = ENV['OAUTH_CLIENT_SECRET']
  config.redirect_uri = 'http://localhost:3000/callback'
end

Authorization Flow

The OAuth 2.0 authorization code flow:

1. Redirect user to authorization endpoint
2. User grants permission
3. Receive authorization code
4. Exchange code for access token
5. Use access token to access protected resources
