Build REST API interfaces with Ecommerce platforms

I am looking for a developer with REST API who can integrate our consumer review system into several ecommerce platforms (see below). It is a significant project which wil take several days but we can spread it across the next 4 to 6 weeks. Per ecommerce platform we need to: Create a developer account (I will do this). Create a merchant account for testing (I will do this). Create a commercial text for [login to view URL] (I will do this). Integrate our [login to view URL] script upon that it is shown on every page of the webshop if the webshop owner activates our app. Connect the API of the ecommerce platform with our API upon that every time a consumer orders a product at the webshop the consumer information: o Webshop URL o gender o email address (mandatory) o phone number o first name o surname o client segment (most platforms will not support this) o language of the customer o country of the customer o order ID Make it extremely easy for the webshop owner to activate our app one click preferably (you) within the app store of the ecommerce platform. Document how to manage the integration in the ecommerce platform so if needed we can update it ourselves in the future (you). The platforms (in order of priority are): Shopify Magento Bigcommerce Prestashop CCV Shop Opencart Lightspeed Zencart OSCommerce 3DCart Oxid esales CScart Woocommerce Shopware xt:commerce Wixstores Weebly VirtueMart Customers GetShopped
