`The task is to create a client that simulates the so-called IPN messages from PayPal, and to create a server application in MVC that handles these messages. How the message will look like you have an example below.
The client can be anything, but perhaps the easiest Windows Forms or MVC. It should be possible to change the values of the sum, your name, address, fees, etc. on the client before sending the message. The message will then be sent in querysträngen from the client and handled by an entity (class) in MVC on the server side. The server application should be a Wep API, the message from the client to be saved in a database. A status message will be returned as JSON from your API controller.
Note it is not permissible to use model binding and sending entity using HTTP POST, you should use querystring!
Any clue how to start?
