  description: >-
    NotificationAPI is notifications infrastructure for developers. A single
    REST API sends multi-channel notifications - email, SMS, mobile push, web
    push, in-app inbox, automated voice call, and Slack - manages user
    identities, enforces per-user notification preferences and opt-outs,
    schedules and retracts notifications, and exposes delivery logs. All
    endpoints are scoped to your account via the clientId path segment and
    authenticated with HTTP Basic auth using clientId:clientSecret.
