Ruby gem for liqpay.ua API

Ruby gem wrapper for official Liqpay SDK https://github.com/liqpay/sdk-ruby

Installation

Add the gem to your Gemfile:

gem 'liqpay', git: 'https://github.com/liqpay/sdk-ruby.git'

And don't forget to run Bundler:

Configuration

Get API keys on https://www.liqpay.ua/ and save them in config (RoR):

# config/initializers/liqpay.rb

::Liqpay.configure do |config|
  config.public_key = 'public_key'
  config.private_key = 'private_key'
end

You can also store API keys in ENV['LIQPAY_PUBLIC_KEY'] and ENV['LIQPAY_PRIVATE_KEY']

And for pure Ruby (liqpay_config.rb for example)

module LiqpayConfig
  def self.configure
    ::Liqpay.configure do |config|
      config.public_key = 'public_key'
      config.private_key = 'private_key'
    end
  end
end

LiqpayConfig.configure

And after that in main.rb or in another each

require 'liqpay'
require_relative 'liqpay_config'

Usage

Full Liqpay API documentation is available on https://www.liqpay.ua/en/doc

  currency:    "USD",
  description: "description text",
  order_id:    "order_id_1",
  version:     "3"
})

Callback

data      = request.parameters['data']
signature = request.parameters['signature']

if liqpay.match?(data, signature)
  responce_hash = liqpay.decode_data(data)
  # Check responce_hash['status'] and process due to Liqpay API documentation.
else
# Wrong signature!
end

Tests

To pass the API tests, specify API keys in ENV['LIQPAY_PUBLIC_KEY'] and ENV['LIQPAY_PRIVATE_KEY'] or in spec/dummy/config.rb:

# spec/dummy/config.rb
::Liqpay.configure do |config|
  config.public_key = 'public_key'
  config.private_key = 'private_key'
end

To run local only tests(keys are not required), execute

rspec --tag ~@real

With real api test you can specify email to recive invoce from Liqpay:

LIQPAY_PUBLIC_KEY=real_public_key LIQPAY_PRIVATE_KEY=real_private_key TEST_EMAIL=real_email rspec --tag @real
