C# with PayPal Donate needs IPN and Mail to payer

There is a PayPal Donatebutton in a C# Form.

Existing PayPal button action:

var url = "[url removed, login to view]" +

@"?cmd=" + "_donations" +

@"&business=" + "mypaypal-mail" +

@"&lc=" + "US" +

@"&item_name=" + "Marlin 3D printer Tool Donation" +

@"&amount=5" +

@"&currency_code=" + "USD" +

@"&bn=" + "PP%2dDonationsBF";

(Missing IPN link)

Existing MANUAL License tool..

When I get the PayPal mail I enter name and email in my C# license tool

A mail is sent to the Donator: (In this case I sent it to myself)

==============================================================

Thank you for your donation!

This license key will remove the Demo mode of the Marlin3DprinterTool

This is the licenseKey for Marlin3DprinterTool

Copy the key and paste it into the Marlin3DprinterTool setup

MANY REGARDS!

Johnny

=============================================================

After the mail is sent the data behind the Base64 string is appended to a file

The file with the donators look like this:
