Hi Bo,

The capture toggle if enabled will capture the payment immediately, if you are wishing to have the capture occur in response to an order changing status then this would need to be done in an event handler.

In the most recent versions of Vendr there is a new IPaymentService (also available on the IVendrApi facade) which you could inject into an event handler and call it's CaptureOrderPayment method.

You're event handler would look something like this

public class CapturePaymentOnOrderStatusChangeHandler : NotificationEventHandlerBase<OrderStatusChangingNotification>
{
    private IVendrApi _vendrApi;

    public CapturePaymentOnOrderStatusChangeHandler(IVendrApi vendrApi)
    {
        _vendrApi = vendrApi;
    }

    public override void Handle(OrderStatusChangingNotification evt)
    {
        // Only proceed if the order is currently authorized
        if (evt.Order.TransactionInfo.PaymentStatus == PaymentStatus.Authorized)
        {
            // Check the order status is changing to completed
            var completedOrderStatus = _vendrApi.GetOrderStatus(evt.Order.StoreId, "completed");
            if (evt.OrderStatusId.To.HasValue && evt.OrderStatusId.To.Value == completedOrderStatus.Id) 
            {
                // Attempt to capture the payment
                var paymentResult = _vendrApi.CaptureOrderPayment(evt.Order);
                if (result.Success)
                {
                    // Apply the changes to the order
                    // --
                    // NB: Because this is a `Changing` event handler
                    // the evt.Order is already writable so not need to
                    // convert it, and also no need to save it as this
                    // will occur automatically.
                    evt.Order.ApplyPaymentChanges(result);
                }
            }
        }
    }
}

Which you'd need to hook up in a composer as documented here https://vendr.net/docs/core/1.8.0/key-concepts/events/#registering-a-notification-event-handler

Hope this helps
