  title: Altostrat Notifications API
  version: 1.0.0
  description: >-
    The Altostrat Notifications API is the microservice responsible for
    creating, configuring, and managing alert routing and delivery channels.


    It acts as the central hub for all platform-generated alerts, ensuring that
    critical events from SD-WAN, network automation, and AI agents are delivered
    to the right people through the right channels at the right time.


    This API allows you to programmatically manage:

    - **Notification Groups:** The core resource that links specific alert
    topics, target sites, and recipients to a notification schedule and delivery
    channel.

    - **Topics:** Pre-defined categories of alerts (e.g., 'WAN Failover',
    'Heartbeat', 'SLA Reports') that users can subscribe to.


    Developers use this API to build sophisticated, context-aware notification
    rules, ensuring that network operators and stakeholders are immediately
    informed of events that require their attention.
