I would like to implement a feature for my app that allows user to import FHIR data into my app. This is exactly same as the new feature of Apple Health to import Health Records
I have read the FHIR specs as well as having the idea how to integrate with FHIR servers (my system contains iOS, Android and web app). The issue is: how can I get access to hospital FHIR server (i.e: have OAuth credentials like app ID, app secret)? Do I need to contact each hospital to get them?
Ideally, I would like to integrate with same hospitals in Apple Health list.
You appear to be talking about US/Argonaut usage. At the moment, you need to contact the vendors - generally, the vendors are issuing application IDs and secrets for use in any hospital that they support
