The official MercadoLibre .NET SDK by MercadoLibre calls the MercadoLibre RESTful API which provides tools to create an online store. This SDK is used to handle the OAuth WebServer flow, and there is no JSON parsing.
InviteBox, social referral program, allows merchants, bloggers, developers (and anybody else with a web presence) to refer friends and customers to recommended products. Users can take advantage of pre-determined referral offers (e.g. coupons, promo codes, free products, cash incentives, etc.) or create custom incentive programs. InviteBox offers all the needed moving parts from creating the referral program to implementation, and the analytics to measure success. Users can simply insert a widget into a website or utilize the Reward Callback API.
