description: >-
  Structured capture of Twilio's product changelog. Unlike date-versioned APIs,
  Twilio does NOT cut a single global dated API version that clients pin via a
  header. Instead the legacy core REST API is fixed at the path version
  /2010-04-01, each product API is versioned independently by subdomain and a
  /vN path (e.g. messaging.twilio.com/v1, verify.twilio.com/v2), and behavioral
  changes, deprecations, and effective dates are communicated through the dated
  changelog. This artifact records the recent changelog window and the
  versioning approach; the live changelog is the source of truth.
docs: https://www.twilio.com/en-us/changelog
versioning:
  scheme: per-product path versioning (no global dated API version or version-pinning header)
  core_rest_api:
    base_url: https://api.twilio.com/2010-04-01
    detail: >-
      The core Twilio REST API is served over HTTPS and carries its version in
      the URL path. 2010-04-01 is the current path version; the earlier
      2008-08-01 version is legacy. Derived from openapi/ and twilio.com/docs/iam/api.
  product_apis:
    pattern: https://<product>.twilio.com/v<N>
    examples:
      - messaging.twilio.com/v1
      - verify.twilio.com/v2
      - voice.twilio.com/v1
    detail: >-
      Product APIs each live on their own subdomain and advance their /vN path
      version independently. Derived from the server URLs and paths in
      /Users/kinlane/GitHub/all/twilio/openapi/.
  client_libraries:
    scheme: semantic versioning (helper libraries, released independently of the API)
    example: twilio-node 6.0.0 raised the minimum Node.js engine from >=14 to >=20
    source: https://github.com/twilio/twilio-node/blob/main/CHANGES.md
  change_communication: >-
    Breaking changes and deprecations are announced ahead of time in the dated
    changelog with an effective date, rather than by minting a new pinned API
    version. Filter facets on the changelog include product (50+ areas such as
    Voice, Messaging, Flex, Segment, Serverless) and type (breaking change,
    deprecation, new feature, announcement).
gap: >-
  Twilio does not publish a single machine-readable "current API version"
  string the way header-pinned date-versioned APIs do, and the changelog is not
  offered as a structured feed on this page. Entries below are transcribed from
  the human-readable changelog; there is no per-entry stable version identifier.

related_client_library_changes:
  note: >-
    Helper-library breaking changes surfaced via the changelog and library
    CHANGES files, versioned separately from the API itself.
  items:
    - Twilio-Sandbox-Mode request header removed from Branded Calls endpoints.
    - Verify version removed from the preview subdomain.
    - highrisk_special_prefixes path parameter renamed from parent_iso_code to iso_code.
    - TwiML Say verb adds SSML support; message body becomes optional.
    - >-
      TwiML Dial behavior change — with a Dial action URL, Twilio requests the
      action callback when the parent call is transferred to new TwiML;
      without one, the parent call continues to the next verb.
