Woocommerce wallet plugin customizations

My website is a shopping marketplace plus price comparision platform. Both sellers and buyers can create account. Sellers are able to create their own products from seller dashboard. I use dokan marketplace plugin for seller management. They have the option of manual withdraw request for their respective earnings. As my website is also a price comparision platform, it have affiliate products from amazon and other marketplaces. What I want is to create a virtual wallet for buyers where they will recieve cashback on specific products and are able to withdraw it directly to bank accounts. Its easy to create a system which will be managed manually by admin but I want it to be done automatically. Hope this will make you clear about my requirements.
