I am integrating Paypal direct payment into my ASP.NET MVC 5 project, by using Paypal's .NET SDK below are the steps: I call PayPal.Api.Payment.Create(APIContext) to navigate user to Paypal site, with the redirect url being a controller's action as callback handler; In the callback action, call PayPal.Api.Payment.Execute(APIContext, ExecutionContext). What I need is pass a parameter (which is order id in my case) when calling Payment.Create(), and receive its value in Payment.Execute(). Is it possible? Thanks a lot.
