Campaigns API

Prerequisites: Campaigns require an approved template (you pass its template_id) and either contact tags or explicit contact IDs as the audience. See Templates API and Contacts API.

Base URL: https://api.vobiz.ai/api/v1/messaging Authentication: Every request requires X-Auth-ID: MA_XXXXXXXX and X-Auth-Token: <token> headers (a Bearer JWT is also accepted). Set Content-Type: application/json on requests with a body. Get your credentials from console.vobiz.ai.
