We introduced a very powerful feature in Sitefinity 4.2 SP 1 that allows you to implement customized code through a post-purchase processing hook in the Ecommerce module. A software developer can create custom code and register the code to be called after two specific events. The first event that can be subscribed to occurs immediately after the payment gateway returns a response. The second event that can be subscribed to occurs after the order is placed. You can write a custom service in either event handler or you may prefer to write one service and execute your custom code just after the order is placed.
There are endless reasons for implementing a web service after these two events. Below are just a few ideas on how you may take advantage of this extendable and powerful new feature in Sitefinity Ecommerce.
To use these events developers should add Global.asax file to SitefinityWebApp project and subscribe to the Ecommerce events.
The Ecommerce specific events can only be registered after Sitefinity’s Bootstrapper has initialized. So, first subscribe to the Bootstrapper.Initialized method. In the Bootstapper_Initialized method you can subscribe to Ecommerce specific events like EcommerceEvents.OrderPlaced or EcommerceEvents.PaymentResponse.
See the code below for an example.
using
System;
using
Telerik.Sitefinity.Abstractions;
using
Telerik.Sitefinity.Modules.Ecommerce;
namespace
SitefinityWebApp
{
public
class
Global : System.Web.HttpApplication
{
protected
void
Application_Start(
object
sender, EventArgs e)
{
Bootstrapper.Initialized +=
new
EventHandler<Telerik.Sitefinity.Data.ExecutedEventArgs>(Bootstrapper_Initialized);
}
void
Bootstrapper_Initialized(
object
sender, Telerik.Sitefinity.Data.ExecutedEventArgs e)
{
if
(e.CommandName ==
"Bootstrapped"
)
{
EcommerceEvents.OrderPlaced +=
new
EcommerceEvents.OnOrderPlaced(EcommerceEvents_OrderPlaced);
EcommerceEvents.PaymentResponse +=
new
EcommerceEvents.OnPostPaymentResponse(EcommerceEvents_PaymentResponse);
}
}
void
EcommerceEvents_PaymentResponse(Telerik.Sitefinity.Ecommerce.Payment.Model.IPaymentResponse paymentResponse)
{
//Write your own customizations
}
void
EcommerceEvents_OrderPlaced(Guid orderId)
{
// Write your own customizations
}
}
}
I am sure you will find this feature very helpful allowing you to integrate customizations that you may need for your online store. All future exposed events will be in the EcommerceEvents class. Upcoming will be another pre-purchase hook that will allow you to write a web service to do anything that you want to do before going into the payment processing section.
We would love to hear about your experiences with these events. We would also like to hear any other specific scenarios that developers might need to make Sitefinity Ecommerce a more extensible product.
