This Node client is a module for interacting with the Shopify API. The client can process OAuth authentication, and then can be used to process GET, POST, PUT and DELETE calls to perform Shopify admin functionalities. The package is actively supported by GitHub contributor sinechris as well as other members of the Shopify developer community.
Over there, by the gum and the tabloid magazines, there's an API. Literally, it's a piece of plastic, but behind it is a company and the APIs that company uses to make the whole operation work. Blackhawk, a subsidiary of Safeway, distributes gift cards for many big-name stores in 90,000 retail locations. And while the cards have always been supported by backend systems, mobile is moving this ten year-old company to an open API approach.
