  Telia publishes no API deprecation policy, no Sunset/Deprecation header support
  and no SLA document on any anonymously reachable surface. What it does publish
  is per-surface versioning and real operational status pages for the underlying
  networks. Recorded honestly: absence is data.
versioning:
  scheme: uri-path
  surfaces:
  - surface: Bulk Messaging SMS REST API
    current: v2
    base_url: https://api.messaging.teliacompany.com/sms/rest/v2
  - surface: LSO Sonata Geographic Site Management
    current: v1
    spec_version: 1.0.1
    base_url: https://api-garden.teliacompany.com/v1/api/mef/geographicSiteManagement
    release_trains:
    - Haley Release
    - R3 Release V1
    - Dolly Release V3
    - Sandbox
    note: the LSO portal groups APIs into named release categories rather than
      semantic versions
  - surface: SMPP API
    current: SMPP 3.4 (interface_version 0x34)
  - surface: ACE Knowledge REST API
    current: valid for widget V1-V4; widget runtime V5 documented separately

  - surface: Telia ACE product
    note: documentation is published per product major version (15.0, 19.0, 21.0,
      31) at docs.ace.teliacompany.com; that host currently redirects every
      deep link to its home page
  document_versioning:
    bulk_messaging_guide: v1.5
    dated: '2026-05-18'
    revision_table: true
deprecation:
  policy_url: null
  sunset_header: false
  deprecation_header: false
  rfc8594: false
  evidence: no deprecation or sunset policy found on developer.teliacompany.io,
    lso.teliacompany.com, camara.teliacompany.com, developer.telia.fi or the Bulk
    Messaging implementation guide
sla:
  url: null
  uptime_target: null
  note: >-
    No published API SLA. Commercial terms are per-API and per-agreement - the
    Telia Developer's Toolbox terms of use state "Fees are connected to
    individual APIs and before usage of an API you will have to enter a separate
    agreement regarding fees for that particular API."
status_page: https://www.telia.se/support/driftinformation-mobilt
status_pages:
- url: https://www.telia.se/support/driftinformation-mobilt
  scope: Telia Sweden mobile network operational status and incident history
  verified: HTTP 200 (nonsense paths on the same host return HTTP 404)
- url: https://www.telia.se/foretag/support/driftinformation
  scope: Telia Sweden business services operational status, filterable by service
    category
  verified: HTTP 200
status_page_note: >-
  These are network/service status pages for the underlying connectivity
  products, not a developer-platform status page. No status page exists for the
  LSO Sonata, CAMARA, Telia Finland or Bulk Messaging API surfaces.
maintenance:
  smpp_patching: >-
    Telia publishes its maintenance protocol for SMPP - the SMSC initiates a
    graceful unbind, the ESME must acknowledge and immediately re-bind, and
    during maintenance windows unbinds are staggered between sessions to
    minimise ESME downtime. Customers can also trigger a graceful unbind
    themselves from the Bulk Messaging portal.
