The Meraki API does provide endpoints for retrieving channel utilization data, but it's typically used for MR Access Points. For Wi-Fi enabled Security Appliances like the MX68CW-NA, the API might not return the same level of detailed radio utilization data as it does for dedicated access points.
You can still retrieve some network health and device status information via the API. For more specific information or alternative endpoints, I would recommend checking the Cisco Meraki Dashboard API documentation.
I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.
