Practice Fusion

Practice Fusion is effectively read-only for third-party integrators. There is no write API for clinical data, no scheduling API, no webhooks, and the developer onboarding path is unclear.

What's hard about this EHR

  • No write API for any clinical data — read-only system for third-party integrators (except HL7v2 lab results for approved partners)
  • No scheduling or appointment API exists
  • No webhooks or event-driven integration capability
  • No functional developer portal or public sandbox
  • FHIR base URL is not publicly discoverable — uses placeholder in documentation
  • PDS API returns C-CDA XML instead of FHIR JSON
