Coupon

What it does

This resource model manages database operations for sales rule coupons in Magento 2.

Developers use it to save, load, and validate coupon codes, check if a coupon exists, retrieve primary coupons for a rule, and synchronize coupon usage limits when rules are updated.

It's the data layer interface for all coupon-related database interactions in the promotional rules system.
