This SDK is a Ruby wrapper for accessing and interacting with the ShipStation API. ShipStation is a shipping service that provides order fulfillment for online retailers. It integrates with USPS, UPS, and FedEx for retrieving rates, creating shipping labels, and more. ShipStation provides a way to ship using branded tracking page shipping software for wherever you sell, however you ship.
One of the key rules of having any service online is the ability to measure everything. Metrics like number of users, requests, where the requests originate, most frequently requested data and many more play an important role in not only fine tuning your services but also give a good measure of what it is going to cost you to run your online business as you scale up. SMSMyBus, a mobile telephone application that lets you find real time bus arrivals for the Madison Metro (WI) has just completed a year of existence and has published a report exactly of that.
