This Perl Sample Source Code is athenahealth's More Disruption Please API samples. The libraries are used to help facilitate access to the API. Each package has a naive implementation of using the API, as well as a library and a testing script to use that library.
APIs will be mandated as a requirement for all health software used in U.S. government-funded healthcare programs starting from 2018. The goal of the initiative is to spur growth of a new healthcare startup ecosystem and to give citizens full control of their health information.
