GuestCouponManagement

What it does

This class manages coupon codes for guest shopping carts in Magento 2.

It acts as a wrapper that converts masked cart IDs (used by guest customers) into real quote IDs before delegating coupon operations to the main coupon management service.

Developers use this class when building guest checkout functionality that needs to apply, retrieve, or remove discount coupons.
