For developers: IWishilstEvent
This interface is implemented by all events that fire after a product is added to a wishlist. There is only one such built-in event and you must subscribe using the interface, rather than the class.
In the event handler, you can access the following information:
- The ID of the product added to the wishlish.
- A list with the IDs of the product variations.
- The ID of the wishlist.
