FHIR Version Support - DSTU2, STU3, and R4

In addition to STU3 Ballot, Interoperablity Engine also offers support for FHIR DSTU2, R4, and the Argonaut Data Query IG profile, so check the capability statement for the FHIR version of the endpoint your app will access or be sure to obtain the endpoint URI for the desired FHIR version, if multiple FHIR versions are available for the datasource.

Please refer to EMR Direct Interoperability Engine Open API documentation (http://www.interopengine.com) on how to connect your client to our public-facing FHIR services.
