Virtual WooCommerce coupons are generated at runtime by hooking the woocommerce_get_shop_coupon_data filter to return a discount data array, satisfying the read_manual_coupon data contract without creating shop_coupon posts in the database.

Yes, rule-based per-user discounts are resolved during checkout by synthesizing coupon data dynamically through code, validating eligibility via woocommerce_coupon_is_valid hooks without requiring database posts.

Custom discount types for virtual WooCommerce coupons are registered by filtering woocommerce_coupon_discount_types, with corresponding discount amounts calculated via the woocommerce_coupon_get_discount_amount hook.

Virtual coupon validation for specific cart items or products uses the woocommerce_coupon_is_valid, _is_valid_for_cart, and _is_valid_for_product hooks to check eligibility rules before applying the dynamic discount.

Yes, external-source coupons are supported by resolving discount rules in code before checkout and order-edit flows, returning the synthesized coupon data array directly through the WooCommerce filter interface.

Generating WooCommerce coupons on the fly requires manual implementation of all validation and discount calculation hooks, as virtual coupons do not exist as shop_coupon posts and cannot be managed through the standard WordPress admin interface.
