Added support for key and Messages for Discount Codes

You can now use user-defined key values to identify Discount Codes. Previously, you could identify them only by their auto-generated IDs. The enhancement also includes a new update action to set the key value, allowing you to update Discount Code keys efficiently without the need to bulk import Discount Codes with the updated keys.

Additionally, this enhancement also adds support for Messages for Discount Codes. You can subscribe to these Messages for changes when creating, deleting, or setting a key value for a Discount Code.
