Attempted using the FHIR R4 APIs for Oracle Health Millennium Platform
to get a practitioner by their NPI using a GET request as follows:
/Practitioner?identifier=http://hl7.org/fhir/sid/us-npi|1518954999
Also have tried using:
/Practitioner?identifier=http://terminology.hl7.org/CodeSystem/v2-0203|1518954999
Nothing seems to work. Is there something I'm missing for this GET EP? Have also tried url encoding and it just doesn't seem to work,
