PayPal Payment¶ ↑

PayPal API Client for Adaptive Payments, Invoice and Express Checkout.

Installation (Gemfile)¶ ↑

gem 'paypal-payment', :git => 'https://github.com/chardy/paypal-payment.git'

Usage¶ ↑

First, you need to set up your credentials:

require "paypal-payment"

PayPal::Api.configure do |config|
  config.sandbox    = true
  config.username   = "chardy_api1.gmail.com"
  config.password   = "8DTSWBZC7GDR3T4X"
  config.signature  = "AG-8mOpuFhFyFOYHlaTUYn3Syf15AWJKRnfHMVsmCtC3DK51-ENEPqLS"
end

Adaptive Payments¶ ↑

You can request a new preapproval authorization:

pa = PayPal::AdaptivePayments::Preapproval.new(
  :client_details => {
    :ip_address => "234.8.8.18",
    :device_id => "123456",
    :application_id => "PP"
  },
  :starting_date => Date.today,
  :currency_code => 'USD',
  :max_total_amount_of_all_payments => 2000.0,
  :cancel_url => 'http://yoursite.com/preapproval/cancel?preapprovalkey=${preapprovalkey}',
  :return_url => 'http://yoursite.com/preapproval/accepted?preapprovalkey=${preapprovalkey}'
)

response = pa.create
puts response.preapproval_url if response.valid?

You need to redirect your user to the url returned by response.approval_url. After the user accepts or rejects your preapproval request, he will be redirected to one of those urls you specified. Note that you need to append “preapprovalkey=${preapprovalkey}” to the urls if you want PayPal to redirect with preapprovalkey You can use the preapprovalkey parameter to query for the approval details.

If you need to retrieve information about your buyer, like address or e-mail, you can use the details() method.

pa = PayPal::AdaptivePayments::Preapproval.new(:preapproval_key => "PA-89578182UL033944H")
response = pa.details

When you need to request payment, create a new Payment with the preapproval key.

pp = PayPal::AdaptivePayments::Payment.new(
  :preapproval_key => "PA-89578182UL033944H",
  :receiver => {:email => "seller@example.com", :amount => 10.0},
  :currency_code => 'USD',
  :cancel_url => 'http://example.com/cancel',
  :return_url => 'http://example.com/thank_you'
)

response = pp.pay
response.success?
response.completed?

You can manage your preapproval.

pa = PayPal::AdaptivePayments::Preapproval.new(:preapproval_key => "PA-89578182UL033944H")
pa.cancel

What information do I need to keep?¶ ↑

You should save two paramaters to your database: TOKEN and PROFILEID. TOKEN is required when user returns to your website after he authorizes (or not) the billing process. You need to save it so you can find him later. You can remove this info after payment and recurring profile are set.

The PROFILEID allows you to manage the recurring profile, like cancelling billing when an user don’t want to use your service anymore.

NOTE: TOKEN will expire after approximately 3 hours.
