Target Corporation is the second-largest discount retailer in the United States. Target uses RESTful APIs to serve enterprise-wide needs, including product data, product locations, inventory, and availability for special purposes such as in-store pick up. When OPI started with Target, these APIs were written using proprietary technology that had very slow delivery times and problematic levels of quality. Target is headquartered in Minneapolis, Minnesota.
OPI demonstrated that using modern non-proprietary technology such as Grails would result in much faster delivery times. OPI also introduced a culture of unit testing, higher-quality code, and continuous delivery. Consequently, Target dramatically sped up their plans for a new generation of APIs.
