OrderStatusSavedNotification vs Validation and email

[KeithViking]

Hi

I want to do some tasks when:

1. Order status is changed under the Commerce area
2. Send Email is clicked.

For

1. I need to add a new order status and then do some inhouse DB work when the status changes to the new one created.

2. I would like to use a 3rd SMTP service. I can add the settings in the config file but i need to add some custom fields for the email template using inhouse settings, images. I suppose i could add it to the template in Commerce but then it would mean the user is having to change this template in 2 places instead of one (on the custom 3rd party email system and Commerce).

3. I tried to add some validation and notification events but they dont register

   public class TestChange : OrderStatusSavedNotification
   {
   public TestChange(OrderStatusReadOnly orderStatus) : base(orderStatus)
   {
   }
   }
   In Composer i regster this and get error
   builder.WithValidationEvent()
   .RegisterHandler();

4. I cant find anyway to customise the email settings. Is there a way or is this the way the system is built so no other option?

Thank you

1. You can create custom order statuses from the back office and then you can listen for the OrderStatusChangedNotification event to trigger your custom action.
2. You can either write the logic for retrieving your values in the email templates razor file, using the passed in model for reference, or you could try implemented a custom email pipeline task to alter the email before it is sent https://docs.umbraco.com/umbraco-commerce/key-concepts/pipelines
3. What was the error?
4. See answer to number 2
