Network Device REST APIs: Automate Without a CLI

Network automation via REST APIs without a CLI: FortiGate (FortiOS REST API), Panorama (Palo Alto), Meraki Dashboard API, and Cisco DNA Center. Python + Requests for rapid scripts and dashboards. 2026 guide.

Why Use REST APIs

• Structured data (JSON) vs. fragile CLI parsing
• No resource-intensive SSH sessions
• Idempotent + stateless
• Multi-language bindings (Python, Go, JS)
• Native support for cloud SaaS platforms (Meraki, Prisma Access)

Authentication

• API key: Meraki (X-Cisco-Meraki-API-Key header)
• OAuth 2.0: Cisco DNA Center, Prisma Access
• Basic Auth: legacy systems
• Token-based authentication: FortiOS
• Certificates: secure mTLS

FortiOS REST API

• URL: https://fortigate.example.com/api/v2/
• Example endpoint: GET /api/v2/cmdb/firewall/policy
• Authentication: token in the header
• Rate limit: 1200 req/min by default

Python example

• import requests
• headers = {'Authorization': 'Bearer TOKEN', 'Content-Type': 'application/json'}
• resp = requests.get('https://fg.example.com/api/v2/cmdb/firewall/policy', headers=headers, verify=False)
• policies = resp.json()['results']
• for p in policies: print(p['name'], p['action'])

Meraki Dashboard API

• Simple + well documented (developer.cisco.com/meraki)
• Python SDK: meraki
• Use cases: automatically create networks and deploy configurations to 1000 devices
• Rate limit: 10 req/s

Cisco DNA Center API

• Token-based OAuth
• Intent API: high-level operations
• Integration API: CRUD operations on resources
• Webhooks: real-time events

Panorama API (Palo Alto)

• XML-based (not JSON)
• Python SDK: pan-python
• Use cases: policy deployment, address objects, and reports

Tools

• Postman: develop and test APIs
• Swagger/OpenAPI: documentation
• Insomnia: an alternative to Postman
• curl: quick CLI access
