  blueprint/tpg-telecom-contacts-management-api.apib plus live probes of
  status.messaging.tpgtelecom.com.au (Atlassian Statuspage) and the Vodafone Business
  Messaging Hub help centre, 2026-07-25.
description: >-
  Versioning, deprecation and operational-transparency posture for the only public API
  surface TPG Telecom operates. The finding that matters: TPG runs a real,
  TPG-branded Atlassian status page for the Messaging Hub — including a dedicated REST
  API component and an Inbound System (Webhooks) component — but publishes no
  deprecation policy, no versioning policy page, no SLA document and no changelog for
  the API itself.
versioning:
  scheme: uri-path
  current: v1
  paths:
    contacts_api: /api/v1/contacts
    messaging_api: /v1
  policy_url: null
  policy_published: false
  note: >-
    Only v1 has ever been published on the TPG-branded host. No version negotiation
    header, no dated version train, and no documented policy for how a v2 would be
    introduced.
deprecation:
  policy_url: null
  policy_published: false
  sunset_header: false
  deprecation_header: false
  note: >-
    No deprecation policy, no RFC 8594 Sunset/Deprecation header support and no
    deprecated operations are declared. The one lifecycle event the help centre does
    document is the platform rebrand to Vodafone Business Messaging Hub, and a
    deprecation of legacy API credentials in favour of Basic/HMAC keys is implied by
    the credential docs but never stated as policy.

  uptime_target: null
  note: >-
    No public SLA or uptime commitment is published for the Messaging Hub API. Plans
    advertise 24/7 email and phone support and a 12-month minimum term; the Critical
    Information Summary on the product page is the nearest contractual document.

changelog:

    No dated API changelog or release-notes surface exists. The help centre carries
    product announcement articles but nothing versioned; the status page incident
    history is operational, not a changelog.
