Contacts Management API for the Vodafone Business Messaging Hub, providing CRUD over contacts, lists and custom fields for SMS/MMS campaigns. Documented as an Apiary API Blueprint (project subdomain contactsapiv1tgp, owner "MessageMedia") embedded in the TPG Telecom Messaging Hub help centre. The blueprint declares the base URI https://api.messaging.tpgtelecom.com.au and 18 operations across /api/v1/contacts/contacts, /api/v1/contacts/lists and /api/v1/contacts/custom-fields. Authentication is HTTP Basic (Base64 api_key:api_secret) or an hmac-sha1 signed Authorization header. No OpenAPI or Swagger document is published — the Apiary project's description format is apiblueprint, and its swagger.json endpoint returns project metadata only.
