I'm reviewing the Shopify APIs and am trying to work out how to connect our internal ERP system to a Shopify site and I'm hoping someone could point me to the correct API or resource. On question I'm running into is we are using Cybersource to handle our payments internally and use tokenization as opposed to storing the credit cards. We would like to charge\refund both on the web and in our internal systems. Is there a way using the Shopify APIs to get the payment token Shopify got from Cybersource in order to process additional charges using our internal system? Also, if a customer orders order via phone, can I upload his/her payment token so that we could take additional payments on the web?
