| Official API (OAuth) | HealOS calls the EHR’s own API with a token you authorize | Approve HealOS in the EHR’s consent screen; some EHRs first need an API app or API access from the vendor | Refreshes tokens, retries rate limits, never asks for a password | Acuity Scheduling, DrChrono, Elation, Halaxy |
| Official API (API credentials) | HealOS calls the EHR’s API with a key or API user you create | An API key or API user, issued in the EHR or by its support team | Stores the credentials encrypted; uses them only for the actions you enable | Cerbo, Hint, ModMed, Tebra, athenahealth (note sending), Acuity Scheduling (API key option) |
| SMART on FHIR | Standards-based FHIR connection approved per health system | Your FHIR base URL (and tenant ID on Oracle Health); your health system enables the HealOS app; a clinician signs in once | Reads the patient, encounter and practitioner; writes the note back as a document | Epic, Oracle Health (Cerner) |
| HealOS cloud browser | For EHRs without a usable API, HealOS signs in to the EHR’s web app from a secure, US-based cloud browser and acts like a careful staff member | A login (ideally a dedicated user), plus the two-factor setup the EHR uses: an authenticator secret, or a code inbox or phone set up with HealOS | Verifies the login before saving; stores credentials encrypted; keeps one signed-in session per practice and renews it during business hours; generates or reads two-factor codes itself | athenahealth, CharmHealth, CurveHero, eClinicalWorks, NextGen Office, Practice Fusion, SimplePractice, TheraNest, TherapyNotes, WebPT |
| Chrome extension | The HealOS extension works inside the clinician’s own signed-in EHR tab | Install the extension and keep the EHR open in Chrome | Fills AI Scribe notes into the open note for the clinician to review and sign; nothing about the EHR login reaches HealOS | AdvancedMD, CureMD, Cliniko, Kalix, Office Ally and others; also many API EHRs for note filling |
| HL7 feed | The hospital’s interface engine sends HL7 v2 messages to HealOS | An interface-engine feed over HTTPS, or MLLP over a site-to-site VPN | Builds patients, appointments and results from the feed for AI Scribe context | Hospital systems such as MEDITECH. See HL7 feeds |
