Open-EMR inbound interface

Hello,

We already downloaded and installed the Open-EMR application. There is some additional information that we need:

  1. When it comes to the interface, is it possible to connect via an external client over http/https?
  2. Is it possible to share the endpoint details?
  3. We need to do a PUSH for demographics and a PULL for Diagnostic Report and Observation using R4. When we do a PUSH, what is the FHIR structure?
  4. What is the inbound standard expected by OpenEMR: HL7 V2 or FHIR?
  5. What are the outbound types: HL7 V2 or FHIR? What is the outbound version of these standards? (V2: 2.3 or FHIR R4 etc)

Thank you in advance
