  notes: >-
    Teladoc Health publishes no dedicated changelog, release-notes feed or
    versioning page for the Solo External API. What exists instead are inline
    release stamps inside the Slate API reference: individual operations carry a
    "Release version" plus the dates the change reached the CAT (customer
    acceptance testing) and PROD environments. Only the operations changed in a
    given release carry a stamp, so this is a partial record of change, not a
    complete history — there is no way for an integrator to subscribe to it or
    to diff two releases.
scheme:
  style: quarterly-release-train
  format: YYYYQn.n
  example: 2026Q1.4
  environments:
  - name: CAT
    role: customer acceptance testing; a release lands here first
  - name: PROD
    role: production; typically 3-5 days after CAT
  api_version: v1
  api_version_note: >-
    The URI version (/qapi/v1) has not moved; release trains ship additively
    inside v1.
entries:
- version: 2026Q1.4
  date_cat: '2026-03-06'
  date_prod: '2026-03-11'
  breaking: false
  additions:
  - POST /qapi/v1/perfect-answer — Perfect Answer integration endpoint that creates
    or updates patient demographics, creates the appointment, attaches the PCM
    template to it and writes the request answers into that template.
  highlights: >-
    Requires waiting-room configuration (Acute Neurology - Physician Services and
    EEG - Physician Services templates), an EHR Mapping location with a
    Geolocation Id, and a PCM template with tagged answers.

- version: 2022Q4.4
  date_cat: '2022-11-25'
  date_prod: '2022-11-29'
  breaking: false
  additions:
  - GET /qapi/v1/appointments/id/type/SAID/value/{solo_appointment_id}/video-call-links
    — retrieve provider and patient video-call links for an appointment addressed
    by its Solo Appointment ID (SAID).
  highlights: >-
    Extended the SAID addressing convention to the video-call-links surface,
    alongside the existing external-appointment-id form.

undated_changes:
  notes: >-
    Later additions appear in the reference without a release stamp — the
    intake:completed webhook event (its example payload is dated 2025-09-12 and
    carries a FHIR-shaped DiagnosticReport body) and the virtual nursing /
    request-assistance surface are both documented with no version or date.
