This guide is written for third party developers, including patients, who are developing software applications for accessing Protected Health Information (PHI) based on this documentation of an open API. This documentation allows applications to query a public-facing API enabled by a data holder. Data holders wishing to publish such a public-facing API should have their Health IT vendor register as a developer integrator of EMR Direct Interoperability Engine services at www.emrdirect.com/subscribe-developer. ALWAYS KEEP IN MIND THAT ONLINE DATA TRANSFER IS NOT A SUBSTITUTE FOR PERSON-TO-PERSON COMMUNICATION OF URGENT OR CRITICAL MEDICAL INFORMATION. This documentation also contains general information and important security information. General information will be marked as “Note:” and important security information will be marked as “IMPORTANT:”.
