Do sandbox or production FHIR APIs applications need to be "certified" with Cerner? We are integrating with our Cerner healthcare client to use FHIR patient search. I have asked them to whitelist our Sandbox Cerner app so that we can develop/test the FHIR patient search but they keep saying that "Setting up a FHIR API is something that the vendor will need to do directly with Cerner/Oracle. They must have it certified through them."
Our integration experts and Cerner documentation seems to indicate that we can self-register our application on Code Console, which we did.
Any guidance would be appreciated.
