Technical Tip: Retrieving data from FortiNAC using REST API

FortiNAC's REST API is a standardized method for other systems to interact with FortiNAC to perform configuration and monitoring operations.

curl --location --request GET 'https://<ha-ip/standalone-ip>:8443/api/v2/device/count/all' --header 'Content-Type: application/json' --header 'Authorization: Bearer <apikey>'

Curl command retrieves the total number of devices managed by FortiNAC in the 'Inventory':

{
"status": "success", <-----
"errorMessage": null,
"results": [],
"filtered": null,
"total": 4 <----- the equals to 4 devices.
}

The following Curl query is just another example of retrieving device identities for hosts available in the 'Hosts' view.

curl --location --request GET 'https://<ha-ip/standalone-ip>:8443/api/v2/host/device-identity' --header 'Content-Type: application/json' --header 'Authorization: Bearer <apikey>'
