Requires `recordings:read`, which is PHI-gated: without a signed BAA the request fails with `403 baa_required`. The signed URL expires shortly after issuance — follow the redirect immediately and do not store or share the URL. Request this endpoint again whenever you need fresh access. The raw storage URL is never exposed. The `Location` header points at `GET /recordings/stream?token=…` on the same host — see that endpoint for the redirect target's auth and error behavior. ## OpenAPI ````yaml /openapi.yaml get /calls/{callId}/recording openapi: 3.1.0 info: title: GrowDental Partner API version: '2026-07-04' summary: >- Programmatic access to GrowDental's voice-AI calling platform for dental practices. description: > The GrowDental Partner API lets platforms and practice-management systems integrate with GrowDental's voice-AI calling for dental practices: list the practices you have been granted, read call results, fetch recordings, trigger outbound calls, and receive signed webhook events. **Status: early access.** This specification is the published v1 contract. Where the deployed API and this document disagree during early access, the discrepancy is a bug — report it and we will reconcile. ### Access Access is **invite-only**. There is no self-serve signup: partner apps, API keys, and practice grants are issued by the GrowDental team. Contact [partners@growdental.ai](mailto:partners@growdental.ai) to get started. ### Conventions - All request and response bodies are JSON; property names are **snake_case** (`duration_seconds`, `next_cursor`, `enabled_events`). - Errors use one envelope everywhere: `{ "error": "", "message": "" }`. - Requests referencing practices your app has **not** been granted return `404` (never `403`), so practice identifiers cannot be probed. - `GET` endpoints never take request bodies; all filters are query parameters. - Pagination varies by resource: the calls list uses cursor pagination (`limit` + `cursor` in, `data` + `next_cursor` out); the call-requests list uses `limit` + `offset` with a `pagination` object; the practices list is unpaginated. - Every `POST` endpoint honors an `Idempotency-Key` header (24-hour replay window). - Timestamps are ISO 8601 / RFC 3339 UTC strings. ### Rate limits Per API key: **600 requests/minute** by default; bulk write endpoints (call-request creation) have a separate **60 requests/minute** budget. Limited requests receive `429 rate_limited` with a `Retry-After` header (seconds). ### PHI and the BAA gate Scopes that expose protected health information (`transcripts:read`, `recordings:read`, `intake:write`) are hard-gated in code: they return `403 baa_required` until a Business Associate Agreement is on file for your app. Webhook payloads are PHI-minimal by design (IDs, outcomes, and links); PHI travels only over authenticated API pulls. contact: name: GrowDental Partnerships email: partners@growdental.ai url: https://voice.growdental.ai servers: - url: https://voice.growdental.ai/api/partner/v1 description: Production security: - bearerAuth: [] tags: - name: Practices description: Practices your partner app has been granted access to. - name: Calls description: Completed and in-flight calls for granted practices. - name: Recordings description: Short-lived, signed access to call recordings (PHI — BAA required). - name: Call Requests description: Trigger outbound voice-AI calls to one or more contacts. - name: Webhook Endpoints description: Manage the HTTPS endpoints that receive signed event deliveries. paths: /calls/{callId}/recording: get: tags: - Recordings summary: Fetch a call recording description: | Redirects (`302`) to a **short-lived signed URL** for the call's audio recording.

Key format: `gd_live_` (or `gd_test_`) followed by a 43-character base62 secret (~256 bits of entropy). To rotate, request a new key, deploy it, then ask us to revoke the old one — both keys work during the overlap. ````
