The Open New York Health Facility Certification Information API is a service part of the State of New York's data.ny.gov open data initiative. The API is meant to assist developers in creating health or healthcare related applications. The API provides access to a searchable dataset that holds information on certifications for New York healthcare facilities, including hospitals, nursing homes, treatment centers, long term healthcare programs, and hospices. The API can be accessed through HTTP communication, and available response types include JSON, XML, and CSV. The documentation features a live testing interface to run example requests. All requests must posses an app token in order to be authenticated.
