Login with Amazon OAuth2 strategy for OmniAuth 1.0

Add this line to your application's Gemfile:

gem 'omniauth-amazon'

And then execute:

$ bundle

Or install it yourself as:

$ gem install omniauth-amazon

You must create an application via the Amazon App Console. Once that is complete, register two URLs under Web Settings -> Allowed Return URLs:

https://localhost:3000/auth/amazon/callback
https://your_website_here/auth/amazon/callback

Amazon requires HTTPS for the whitelisted callback URL (except localhost). They don't appear to like .dev domains too much but happily accept localhost.

Usage is similar to other OAuth2 based OmniAuth strategies:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :amazon, ENV['AMAZON_CLIENT_ID'], ENV['AMAZON_CLIENT_SECRET'],
    {
      :scope => 'profile postal_code' # default scope
    }
end

Config options can be passed to provider via a Hash:

• scope: A space-separated list of permissions. Can be profile, postal_code, profile:user_id, or a combination of options.
  Defaults to: profile postal_code
  • Requesting the profile:user_id scope will not display an additional consent screen the first time the user logs in.

• Login with Amazon button guide
• Login with Amazon style guide
