Hello,
Regrettably, no documentation related to this topic is availabe. In general, you will need to override methods that generate notification emails and implement them according to your requirements:
// Send order notification emails
OrderInfoProvider.SendOrderNotificationToAdministrator
OrderInfoProvider.SendOrderNotificationToCustomerFor more information about customizing e-commerce methods, I would like to point you to the following blog:
E-commerce 6 New customization model.
Best regards,
