  Versioning, deprecation and operational-transparency posture for the ActiveCampaign
  API. The honest headline: ActiveCampaign runs three API generations concurrently and
  publishes a migration table, but has no written deprecation policy, no Sunset/
  Deprecation header support, and no public SLA.
versioning:
  scheme: uri-path
  current: v3
  path_segment: /api/3
  docs: https://developers.activecampaign.com/reference/url
  generations:
    - version: v3
      status: current
      base: 'https://{yourAccountName}.api-us1.com/api/3'
      specs:
        - openapi/_original/activecampaign-v3.json
        - openapi/activecampaign-whatsapp-api-openapi.yml
        - openapi/activecampaign-segments-api-openapi.json
        - openapi/activecampaign-segment-matching-api-openapi.json
        - openapi/activecampaign-segment-match-one-api-openapi.json
    - version: v2
      status: legacy-but-live
      base: 'https://{youraccountname}.api-us1.com/api/2'
      spec: openapi/activecampaign-v2-api-openapi.json
      surviving_operations: 1
      note: >-
        Still advertised in ActiveCampaign's own /.well-known/api-catalog as a live
        service description. One operation remains: GET /api/2/template/share
        (create-shareable-campaign-template-link). No end-of-life date is published.
    - version: v1
      status: retired
      note: >-
        Retired but still addressed in the docs. The v3 account endpoint carries a
        field-by-field v1 -> v3 migration table (account_view -> GET /settings/account,
        fname -> first_name, result envelope removed in favour of HTTP status codes),
        which is the only migration guidance ActiveCampaign publishes anywhere.
      migration_guide: https://developers.activecampaign.com/reference/retrieve-account-information
  breaking_change_notice: undocumented
deprecation:
  policy_url: null
  policy_published: false
  sunset_header: false
  deprecation_header: false
  rfc8594: false
  note: >-
    No deprecation policy page exists on the developer portal, no notice period is
    stated, and no operation in any of the nine published specs carries
    `deprecated: true`. v1 was retired without a published sunset date and v2 has been
    reduced to a single operation with no announced end of life. An integrator has no
    contractual warning of removal.
deprecated_operations: []
deprecated_operation_count: 0
sla:
  url: null
  published: false
  uptime_target: null
  note: >-
    No public SLA or uptime commitment is published for the API. Uptime is observable
    through the status page but is not promised.
status_page:
  url: https://status.activecampaign.com/
  provider: Atlassian Statuspage
  machine_readable: https://status.activecampaign.com/api/v2/summary.json
  subscribe: true
  note: >-
    Statuspage v2 API is live and anonymous, so an agent can poll component health and
    incident history programmatically — the strongest operational-transparency signal
    ActiveCampaign offers.
