description: >-
  Versioning, deprecation, status and support posture for the Synthflow Platform API.
  Synthflow runs a continuous, dated changelog that carries an explicit "Deprecation
  Notices" category, and a real Statuspage with per-component health. It publishes no
  numeric SLA target outside an enterprise contract, and no Sunset/Deprecation header
  support.

versioning:
  scheme: uri-path
  current: v2
  docs: https://docs.synthflow.ai/api-reference/platform-api
  header_negotiation: false
  policy_published: false
  note: >-
    Every published server URL is /v2. There is no documented policy for how a breaking
    change is introduced, how long a prior version is supported, or how a caller pins one.

deprecation:
  policy_url: null
  policy_published: false
  announcement_channel: https://docs.synthflow.ai/changelog
  changelog_category: Deprecation Notices
  sunset_header: false
  deprecation_header: false
  rfc8594: false
  observed_notices:
    - {date: '2026-07-29', title: 'Stripe-based reselling is ending', category: Deprecation Notices}
  note: >-
    Deprecations ARE announced, and are tagged as their own filterable category on the
    changelog — that is a real, working deprecation communication channel. What is missing
    is a written policy (notice period, support window) and runtime signalling: no Sunset
    or Deprecation response headers, and no operation in the OpenAPI is marked
    `deprecated: true`.

deprecated_operations: []
deprecated_operations_note: >-
  Zero of the 100 operations in openapi/_original/synthflow-openapi.json carry
  `deprecated: true`.

breaking_change_signalling:
  in_changelog: true
  example:
    date: '2026-08-05'
    title: 'Phone numbers API: Five9, RingCX, and required SIP domain'
    change: >-
      termination_uri (SIP domain) became REQUIRED on POST /custom-numbers for all
      providers except Five9, RingCX and Zoom.
    breaking: true
    note: >-
      A required-field addition on an existing operation, announced in the changelog but
      not versioned and not surfaced through any header. Callers find out by reading the
      changelog or by failing.

status_page:
  url: https://status.synthflow.ai/
  provider: Atlassian Statuspage
  api: https://status.synthflow.ai/api/v2/summary.json
  machine_readable: true
  components: ['End to End calling', 'Synthflow Dashboard', 'Synthflow API', 'Synthflow Website']
  observed_status: 'All Systems Operational'
  observed_at: '2026-08-13'
  note: >-
    The API is broken out as its own component, separate from the dashboard and the
    website, and the Statuspage v2 JSON API is reachable unauthenticated — a subscribable,
    agent-readable health signal. The changelog records an "Improved System Status page"
    entry on 2026-07-16.

sla:
  url: null
  uptime_target_marketing: '99.99%'
  contractual: 'Enterprise SLA and support terms are scoped in contract.'
  source: https://synthflow.ai/pricing
  note: >-
    99.99% is a marketing claim on the product surface, not a published SLA document with
    remedies. The pricing page states SLA and support terms are scoped per enterprise
    contract.
