It is a small but powerful web application for matching the categories of the product providers with the categories of the seller that have been defined in an Opencart e-commerce system. The categories of the product providers are extracted from their xml exports published at web addresses. The categories of the seller are obtained from their provided API based on OAuth 2.0 protocol. The matching results are exported as a set of Excel functions which can be used for importing the products data from the provider xml file into the seller Opencart system. The system has been developed using TPS Framework. Also the JQuery AJAX technology has been used for obtaining the seller categories from their Opencart system.
