Eshop with api connection from kinguin.com

Hello need crate eshop with api integration from kinguin I need to integrate the payment gateway, preferably [login to view URL] At the moment I only have a domain, so I need a complete solution. then I will need to translate everything into the Czech language however, I will do it myself, I just need to be able to translate everything 1.) import of products from the supplier API - this is done regularly, on a daily basis, including product updates - price conversion by formula, categorization (categorization) according to the client's request, 2.) customer purchase via e-shop card, 3.) awaiting payment (payment gateway, account) after order confirmation 4.) after payment, from the vendor via API, requested license key (s) for the ordered products, 5.) these are sent to the customer via e-mail e-shop 6.) the customer in his account and also the administrator, sees the assigned license keys of the individual order, 7.) the system ensures that the key is not ordered twice. The order is logged into the system so that it can be traced back and, in the event of a problem, requested from the supplier and forwarded to the customer. At the same time, the system, in the administration, contains actions (buttons) through which it is possible to resend the e-mail with the keys or request them again from the supplier.
