Shopify Multipass module for Ruby

Shopify provides a mechanism for single sign-on known as Multipass. Multipass uses an AES encrypted JSON hash and multipassify provides functions for generating tokens

More details on Multipass with Shopify can be found here.

    gem install multipassify

To use Multipass an Enterprise / Plus plan is required. The Multipass secret can be found in your shop Admin (Settings > Checkout > Customer Accounts). Make sure "Accounts are required" or "Accounts are optional" is selected and Multipass is enabled.

  require 'multipassify'

  # Construct the Multipassify encoder
  multipassify = Multipassify.new 'SHOPIFY MULTIPASS SECRET'

  # Create your customer data hash
  customer_data = { email: '[email protected]', remote_ip:'USERS IP ADDRESS', return_to:"http://some.url"}

  # Encode a Multipass token
  token = multipassify.encode(customer_data)

  # Generate a Shopify multipass URL to your shop
  url = multipassify.generate_url(customer_data, 'yourstorename.myshopify.com')

  # Generates a URL like:  https://yourstorename.myshopify.com/account/login/multipass/<MULTIPASS-TOKEN>
