What HealOS does in TheraNest

AI Frontdesk

What the AI Frontdesk (AI Receptionist) can do in TheraNest during a call:

Task	Available
Find the caller’s chart	Yes
Register a new patient	Yes
Find open slots	Yes
Book an appointment	Yes
Look up upcoming appointments	Yes
Cancel an appointment	Yes
Reschedule an appointment	Yes

Connect it from AI Frontdesk → Integrations → Connect an EHR (Connect your EHR).

AI Scribe

AI Scribe notes cannot be sent to TheraNest yet; copy the note from HealOS.

Connection

Method: HealOS cloud browser. How the methods compare. You provide

A TheraNest email and password, in AI Frontdesk → Integrations → Connect an EHR. HealOS finds your practice address itself.

HealOS does

Checks the sign-in before saving anything: a login that fails is not stored.
Stores the credentials encrypted and signs in from a secure, US-based cloud browser.
Keeps one signed-in session per practice and renews it during business hours, so calls don’t wait for a login.
Cancels by setting the appointment’s status to Canceled; it never deletes appointments.

Yes: works once the practice connects the EHR (or, for the Chrome extension, installs it).
On request: built; HealOS turns it on for a practice after a review with them.
Specific setups: built for particular practice configurations; ask us before relying on it.

A Yes means the workflow exists, not that every practice’s setup allows it: practice settings, user permissions and the EHR plan can still limit it, so confirm during onboarding.

API actions

This is a catalog of what HealOS can do in each EHR. Running these actions through the HealOS API is coming later. Listing them (GET /ehr/actions) and checking which EHRs your organization has connected (GET /ehr/connections), with the ehr:read scope, are rolling out: they work on staging but are not yet available on api.healos.ai. Every action runs against the practice’s live EHR, never a sandbox.

HealOS supports 7 actions in TheraNest. Action names (theranest.<action>) are stable.
