I used a different website and ecommerce service before and am in the process of switching over to Shopify, but I want to keep VinNOW, the POS I was using. VinNOW has a way to send and recieve data from a web shopping cart service, but they expect the format to be XML/SOAP, not json. VinNOW has a form in their program to enter a Web Service URL, Web Service Namespace, User ID, and Password. I created a private app in the hopes that the API key would work to integrate the two services. It seems like I need to find or create a way to translate between json and xml.
