I am developing a FHIR based healthcare model and am currently connecting to multiple EMR vendors. The authentication API is returning “invalid client” response in case of production client ID. On the other hand, we get our access token successfully for further API calls for non-production/sandbox client ID. For reference, working in EPIC currently, with no affiliation.
How do we get EPIC production API access? Will I have to reach out to each institution to plug in? I am mostly trying to pull anonymized location and disease data.
