WooCommerce to G2A Integration Plugin

Hi! I need help with integrating G2A API with woocommerce! G2A API Docs: [login to view URL] Features: 1) A setting page where you will enter list of IDs(G2A Product IDs) which you want to sync with your woocomerce store 2) You will have to impiort those products once from that page 3) Then plugin will have a cron job set which will sync product stock and price dialy(or as we are able to do with server configuration allowed) 4) G2A only consider one products per order. So, we will have to set that limitation on your woocommerce store for G2A products(and will also have to restirct G2A products to be purchased with other products of your store) 5) Plugin will have option to sync products details manually via API for specific product 6) Product Key will be sent to customer with/in order email as soon as order goes to "Processing" status and once key will be fetched from G2A, order will be marked as "Completed". In case of any error/issue with getting Key from API, admin can manully process again for order to get Key for that order and send an additional email to send Key to customer. 7) Product name, Category, Price, Stock, Images will be imported from API. If you want other details like release date, region, restrictions, and requirements etc to be imported as Product description on woocommerce then let me know. 8) Plugin will send an email to admin whenever any Order get failed on G2A due to low credit balance.
