Working with payment states

Due to security reasons, the payment state machine is restricted. However related states to payment states can be added, which will cause the order state or the delivery state to transfer when a payment goes to a particular state. There is a working example in "Add related state" article.

Default implementation

Following example shows how the related states are added in the default implementation, which is present in PaymentStateBuilder class.

For example, when the payment is paid, an attempt is made to put the order to Processing, or to Completed. In the default implementaiton of order state machine Order will go to processing, if the delivery is not yet completed when payment is Paid, or order will go to completed if the delivery is already completed when the payment is paid.

/// <summary>

       /// Builds related transitions to payment state.
        /// </summary>
        /// <param name="stateManager">State transitions manager.</param>
        internal virtual void BuildStateTransitions(StateTransitionsManager stateManager)
        {
            //..other code.
            //If payment is completed, order state should be in either processing or completed.
            stateManager.AddRelatedStateToPaymentState((short)PaymentStatus.Paid, FiniteStateMachineType.Order, (short)OrderState.Processing);
            stateManager.AddRelatedStateToPaymentState((short)PaymentStatus.Paid, FiniteStateMachineType.Order, (short)OrderState.Completed);

            //..other code
        }
