OmniAuth Shopify

Shopify OAuth2 Strategy for OmniAuth 1.0.

Installing

Add to your Gemfile:

gem 'omniauth-shopify-oauth2'

Then bundle install.

Usage

OmniAuth::Strategies::Shopify is simply a Rack middleware. Read the OmniAuth 1.0 docs for detailed instructions.

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 :shopify, ENV['SHOPIFY_API_KEY'], ENV['SHOPIFY_SHARED_SECRET']
end

Configuring

You can configure the scope, which you pass in to the provider method via a Hash:

  • scope: A comma-separated list of permissions you want to request from the user. See the Shopify API docs for a full list of available permissions.

  • setup: A lambda which dynamically sets the site. You must initiate the OmniAuth process by passing in a shop query parameter of the shop you're requesting permissions for. Ex. http://myapp.com/auth/shopify?shop=example.myshopify.com

For example, to request read_products, read_orders and write_content permissions and display the authentication page:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :shopify, ENV['SHOPIFY_API_KEY'], ENV['SHOPIFY_SHARED_SECRET'],
            :scope => 'read_products,read_orders,write_content',
            :setup => lambda { |env| params = Rack::Utils.parse_query(env['QUERY_STRING'])
                                     env['omniauth.strategy'].options[:client_options][:site] = "https://#{params['shop']}" }
end

Authentication Hash

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

{
  :provider => 'shopify',
  :credentials => {
    :token => 'afasd923kjh0934kf', # OAuth 2.0 access_token, which you store and use to authenticate API requests
  }
}
