  title: Juniper Networks Juniper Apstra Intent-Based Networking Alarms API
  description: RESTful API for Juniper Apstra, an intent-based networking platform for automating data center network design, deployment, and operations. Apstra abstracts network infrastructure into design blueprints with logical models, rack types, templates, and connectivity. The platform continuously validates that the network state matches the intended configuration and raises anomalies when deviations occur. The API provides full access to design resources, blueprints, device management, telemetry, and IBA (Intent-Based Analytics) probes. Authentication uses token-based sessions obtained via the login endpoint.
