Practice Fusion API integration guide: PDS partner registration and FHIR

The short answer

Practice Fusion, owned by Veradigm, offers a read-only FHIR R4 API through its Patient Data Sharing (PDS) partner registration. Practices control which apps can see their data. There's no published write or scheduling API for Practice Fusion; Veradigm's read-write Unity API belongs to its other EHR family.

How access works

1. Complete the PDS API partner registration and accept the terms.
2. After approval, log in to the PDS portal and submit your app: type (patient, provider or system/bulk), JWKS URL, redirect and launch URLs, scopes.
3. Receive credentials. Practices then allow or deny your app in the EHR.

What the APIs cover

What it costs

Practice Fusion's published fee schedule states no API fees for development, deployment or usage at this time, and a no-cost FHIR licence (schedule last updated May 2024, accessed 11 Oct 2026; may change with notice).

Our take

Practice Fusion is cheap to read from and closed to write into. If your product needs to book or file, plan a practice-authorized alternative that respects Veradigm's terms, or prioritize EMRs with documented write.
