Active PayPal Adaptive Payment

This library is meant to interface with PayPal's Adaptive Payment Gateway.

• Payments
• Preapprovals
• Refunds
• Currency conversions
• getting/setting payment options
• getting shipping addresses
• getting a redirect for the embedded pay flow
• More soon!

Add the following line to your app Gemfile:

gem "active_paypal_adaptive_payment"

bundle install

See iAuction: An Adaptive Payments Tutorial Featuring Parallel Payments tutorial for more info.

gateway =  ActiveMerchant::Billing::PaypalAdaptivePayment.new(
  :login => "acutio_1313133342_biz_api1.gmail.com",
  :password => "1255043567",
  :signature => "Abg0gYcQlsdkls2HDJkKtA-p6pqhA1k-KTYE0Gcy1diujFio4io5Vqjf",
  :appid => "APP-80W284485P519543T" )

gateway.preapprove_payment (
  :return_url => "returnURL",
  :cancel_url => "cancelURL",
  :senderEmail =>"email address of sender",
  :start_date => Time.now,
  :end_date => Time.now + (60*60*24) * 30,
  :currency_code =>"currency code",
  :max_amount => "maxTotalAmountOfAllPayments",
  :maxNumberOfPayments => "maxNumberOfPayments" )

  response = gateway.setup_purchase(
    :return_url => url_for(:action => 'action', :only_path => false),
    :cancel_url => url_for(:action => 'action', :only_path => false),
    :notify_url => url_for(:action => 'notify_action', :only_path => false),
    :receiver_list => recipients
  )

# For redirecting the customer to the actual paypal site to finish the payment.
redirect_to (gateway.redirect_pre_approval_url_for(response["payKey"]))

 gateway.cancel_preapproval(:preapproval_key => "preapprovalkey")

def checkout
  recipients = [{:email => 'receiver_email',
                 :amount => some_amount,
                 :primary => true},
                {:email => 'receiver_email',
                 :amount => recipient_amount,
                 :primary => false}
                 ]
  response = gateway.setup_purchase(
    :return_url => url_for(:action => 'action', :only_path => false),
    :cancel_url => url_for(:action => 'action', :only_path => false),
    :ipn_notification_url => url_for(:action => 'notify_action', :only_path => false),
    :receiver_list => recipients
  )

  # For redirecting the customer to the actual paypal site to finish the payment.
  redirect_to (gateway.redirect_url_for(response["payKey"]))
end

Set the :primary flag to false for each recipient for a split payment.

Maybe also check the tests for a sample implementation.

Notes:

In development environment it's very important to define ActiveMerchant environment you will be using to test your app like so:

#config/environments/{environment.rb}
App::Application.configure do
  config.setting...
end
ActiveMerchant::Billing::Base.mode = :test

To be able to set additional payment and invoice options, such as item names, shipping costs, custom logos, etc., you must first create a payment, then set the options and then direct the user to the payment page:

purchase = gateway.setup_purchase(
  :action_type => "CREATE", # This is in contrast to the default PAY action
  …                         # as above
)

gateway.set_payment_options(
  :display_options => {
    :business_name    => "Your Business",
    :header_image_url => "http://cdn.yourbusiness.com/logo-for-paypal.png"
  },
  :pay_key => purchase["payKey"],
  :receiver_options => [
    {
      :description => "Your purchase of XYZ",
      :invoice_data => {
        :item => [
          { :name => "Item #1", :item_count => 1, :item_price => 100, :price => 100 },
          { :name => "Item #2", :item_count => 2, :item_price => 10, :price => 20 }
        ],
        :total_shipping => 5,
        :total_tax => 10
      },
      :receiver => { :email => "receiver1@example.com" }
    },
    {
      :description => "XYZ Processing fee",
      :invoice_data => {
        :item => [{ :name => "Fee", :item_count => 1, :item_price => 10, :price => 10 }]
      },
      :receiver => { :email => "receiver2@example.com" }
    }
  ]
)

redirect_to(gateway.redirect_url_for(purchase["payKey"]))

See the implementation of ActiveMerchant::Billing::PaypalAdaptivePayment#build_adaptive_set_payment_options_request for all available options and Operation SetPaymentOptions API for a description of them.

First modify the test/fixtures.yml to fit your app credentials (You will need at least a PayPal developer account).

After that you can run them like this:

$ ruby -Ilib test/test_paypal_adaptive_payment.rb

Use either gateway.debug or response.debug this gives you the json response, the xml sent and the url it was posted to.

From the Rails console it can be accessed like such:

ActiveMerchant::Billing::PaypalAdaptivePayment

PaypalAdaptivePayment#debug or AdaptivePaymentResponse#debug return the raw xml request, raw json response and the URL of the endpoint.

• More/better Documentation.
• Improve/change the tests implementation by maybe run them off fixture data and use a separate script/test for actually invoking requests to PayPal. This will allow other developers to implement the without being required to set and request the credentials from PayPal process.
