How do I process a response from a remote REST API (Paypal)?

Question

I'm trying to figure out the Paypal REST API .

I have an action for the ReturnURL ( /payment/return ) and an action for the CancelUrl ( /payment/cancel ).

When I generate the Payment: Payment createdPayment = pymnt.Create(this.accessToken);

I get the approved_url which I need to redirect for my user so he/she can make the actual Paypal Payment. When the user is done, Paypal sends back an approved Payment object (JSON).

I am trying to get my hands on that JSON in the return action so it will bind to the Payment object.

This does not work:

public ActionResult Return(Payment payment)
{
    payerId = Request.Params["PayerID"];
    var paymentId = payment.id; // NullException
    var result = paypalService.ExecutePayment(paymentId, payerId);
    return this.View();
}

How do I bind the response JSON?

Answer 1

just to read json there are many ways to do this but if you do not want to bind you can use dynamic

   dynamic reply= JsonConvert.DeserializeObject(jsonstring)

also take a look at this
