Convert IPN to XML

Rolosoft.com: PayPal IPN Easy for .NET

You can easily convert PayPal IPN messages into XML with just a few lines of code.

The following example shows how to implement an IPN listerner and write the IPN to an XML file on the local drive.

Create an ASPX page to receive PayPal IPNs

Create Xml.aspx

namespace IpnEasyDemo
{
    public partial class Xml : Page
    {

        protected void Page_Load(object sender, EventArgs e)
        {
            _ipnEasy = new Rolosoft.IpnEasy.Net.Ipn();
            _ipnEasy.TransactionReceived += IpnEasyTransactionReceived;
            _ipnEasy.Validate();
        }

        private static void IpnEasyTransactionReceived(object sender,Rolosoft.IpnEasy.Net.PayPal.TransactionEventArgs e)
        {

            //Serialize and save the IPN to local disk.
            //Note: You will need to give write permission to the IIS process (e.g. NETWORK SERVICE) to write the file to local disk
            var ser = new XmlSerializer(typeof(Rolosoft.IpnEasy.Net.PayPal.Transaction));
            using (var fs = new FileStream(String.Concat(@"c:\", e.Transaction.TransactionAndNotification.TxnId, ".xml"),

Post an IPN to your .aspx page

Using the PayPal developer sandbox IPN test tool, post an IPN to your test page.

Note:
If you are using the PayPal developer sandbox IPN test tool, your IPN listener must be visible from the internet.

It may be possible to configure your router to use NAT port redirection to allow you to use the PayPal sandbox IPN test tool to send IPN messages to your local development machine. If you need assistance with this, please consult your network administrator.

View the saved XML file

The saved XML file can be found in the root of C:\ drive and saved with the file name {TxnId}.xml where TxnId is the PayPal transaction Id.
