Practice Fusion Patient Fusion PHR API
Patient-facing personal health record API documented in the PDS API Developer Guide. Serves a patient their own clinical documents and record data from the Practice Fusion EHR, authorized with OAuth 2.0 plus OpenID Connect through the Patient Fusion identity provider at auth.patientfusion.com, which publishes a full OIDC/RFC 8414 discovery document anonymously. Distinct from the FHIR PDS API: it uses a proprietary JSON surface with its own status-code table (including 300 Multiple Choices for an ambiguous patient match) rather than FHIR OperationOutcome.
