Not only can we develop endpoints for command and publish/subscribe messages, but we can also develop sagas in ServiceMatrix. We will start by creating a new command message, PaymentNotification.

The copy preview box will appear again as we copy the sending of the new command message to the message handler:

  public partial class PaymentAcceptedHandler
    {

        partial void HandleImplementation(PaymentAccepted message)
        {
            // TODO: PaymentAcceptedHandler: Add code to handle the PaymentAccepted message.
            Console.WriteLine("Paying received " + message.GetType().Name);
            var paymentNotification = new PaymentEngine.Internal.Commands.Paying.PaymentNotification();
            Bus.Send(paymentNotification);
        }
    }

We will deploy the receiving endpoint on to a new endpoint called NotifyProcessing.

This is what we should have so far:

To start the saga process, we need to click on Reply with Message....

This will allow us...
