I have used Google Translate to understand your query. I believe you want to have a custom coupon generator that keeps track of the coupons in your WordPress admin area.

It’s understandable that all coupon-related plugins are targeted to WooCommerce. Most of the time coupons are supposed to be used with a product purchase.

Since this is not about WooCommerce rather for WordPress core. I will recommend posting this on WordPress Forums.

Thank you ??
