Veradigm Unity API
Veradigm's proprietary bidirectional API and the only Veradigm surface that can WRITE patient demographic, appointment or financial data - the Process Overview page states plainly that the FHIR API is read-only for deeper integration purposes and that Unity is required to read or write against Veradigm Practice Management. Unity is also the recommended app-launch path for Veradigm EHR versions before 24.5. No public reference, base URL, OpenAPI or sandbox is published: access requires a paid Veradigm Connect Integrator subscription (Bronze through Platinum Plus) and Veradigm certification. No base URL is recorded here because Veradigm publishes none.
