Coupon redemption form and Wordpress WPLMS integration

I need a plugin, which will create a form to validate coupons from Groupon, Atrapalo, etc. and that is integrated with WPLMS. The plugin will consist of a frontend and a backend. The frontend will be a page with a form, where the user will upload a document or a screenshot of the coupon, if the customer is registered will be automatically added to the user, and if it is not, will be asked for registration data. The backend will be a series of pages, where the main one is the list of redeemed coupons, to be able to validate them; another one will be for configurations, another one to register/unregister companies selling coupons. Once the coupon is validated in the backend, the customer will be automatically enrolled in the course. I want the plugin to be prepared to make the process completely automatic in the future. The website is in Spanish.
