Parser and handler for incoming Instant payment notifications from paypal. The Example shows a typical handler in a rails application. Note that this is an example, please read the Paypal API documentation for all the details on creating a safe payment controller.
Example
class BackendController < ApplicationController include ActiveMerchant::Billing::Integrations def paypal_ipn notify = Paypal::Notification.new(request.raw_post) order = Order.find(notify.item_id) if notify.acknowledge begin if notify.complete? and order.total == notify.amount order.status = 'success' shop.ship(order) else logger.error("Failed to verify Paypal's notification, please investigate") end rescue => e order.status = 'failed' raise ensure order.save end end render :nothing end end
Acknowledge the transaction to paypal. This method has to be called after a new ipn arrives. Paypal will verify that all the information we received are correct and will return a ok or a fail.
Example:
def paypal_ipn notify = PaypalNotification.new(request.raw_post) if notify.acknowledge ... process order ... if notify.complete? else ... log possible hacking attempt ... end
This is the item number which we submitted to paypal The custom field is also mapped to item_id because PayPal doesn‘t return item_number in dispute notifications
When was this payment received by the client. sometimes it can happen that we get the notification much later. One possible scenario is that our web application was down. In this case paypal tries several times an hour to inform us about the notification
