zapient / active_merchant_square

Square's e-commerce API support added to Active Merchant. (This depends on core active merchant, so it can coexist peacefully with upstream changes there. Not merged into Active Merchant for reasons as described here https://github.com/activemerchant/active_merchant/pull/2242) See example below, and our blog post: https://medium.com/square-corner-blog/activemerchantsquare-for-squares-e-commerce-api-111ea63e530a

Active Merchant Square

Installation

Add this line to your application's Gemfile:

gem 'active_merchant_square'

And then execute:

$ bundle

Or install it yourself as:

$ gem install active_merchant_square

Usage

This simple example demonstrates how a purchase can be made after getting a card nonce

require 'active_merchant_square'

# Get your login and password by going to: https://connect.squareup.com/apps
credentials = {
  login: 'sandbox-sq0idp-APPLICATION_ID',
  password: 'sandbox-sq0atb-APPLICATION_SECRET',
  # How to get your location ID, see: https://docs.connect.squareup.com/articles/faq-lookup-my-location-id
  location_id: 'LOCATION_ID',
}

amount = 1000  # $10.00

gateway = ActiveMerchant::Billing::SquareGateway.new(credentials)
response = gateway.purchase(amount, card_nonce)

if response.success?
   puts "Successfully charged $#{sprintf("%.2f", amount / 100)}"
else
   raise StandardError, response.message
end
