Fortinet firewall and FortiGate VDOM REST-based discovery

  • Release version: Australia
  • Updated March 12, 2026
  • 5 minutes to read

    • The Discovery and Service Mapping Patterns application uses the Next Generation Fortinet Network Firewall - REST pattern to find Fortinet firewalls through REST API calls. Additionally, the pattern extension VDOM Discovery finds FortiGate Virtual Domains (VDOMs). Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

    The Next Generation Fortinet Network Firewall - REST pattern uses a set of REST API calls to find the Fortinet firewalls. For FortiGate VDOM discovery, only multi-VDOM mode is supported.

    Note:
    Only the REST-based Fortinet firewall discovery method finds FortiGate VDOMs. The SNMP-based Fortinet firewall discovery method doesn't discover them. For information about the default SNMP-based Fortinet firewall discovery, see Next-Generation Fortinet Network Firewall SNMP-based discovery.

    Prerequisites

    Verify that the applications are up to date
    • Discovery and Service Mapping Patterns
    • CMDB CI Class Models
    Create API Token
    Create an API Token in Fortinet. For instructions on creating an API Token, go to the Fortinet Document Library and search for the "Connect FortiGate device via API Token - Online Help" article under the FortiConverter Tool product family.
    Verify API access and permissions
    • Verify that the MID Server can access the Fortinet APIs.
    • Verify that the API Token has sufficient permissions to retrieve the required information from the Fortinet devices.
    Required Fortinet APIs:
    • v2/cmdb/system/global
    • api/v2/monitor/system/status
    • api/v2/cmdb/system/ha
    • api/v2/cmdb/router/static

    • /api/v2/monitor/system/interface/select
    Disable SNMP-based Fortinet firewall discovery
    For more information, see Disable SNMP-based Fortinet firewall discovery.
    Create an alias for the API Key Credentials
    For more information, see Create an alias for the API key credential for Fortinet firewall REST-based discovery.
    Create a serverless discovery schedule
    For more information, see Create a serverless schedule for Fortinet firewall REST-based discovery.
