Meraki Get Network Events API - not returning clientMac

PWJPW — Wed, 26 Aug 2026 16:07:13 GMT

We have an org with 15 networks. We're calling the following endpoint to pull some wireless event detail (client associations):

https://developer.cisco.com/meraki/api-v1/get-network-events/

However, one a few of our networks (but not all), the clientMac is null on the returned data, whereas on most networks, its populated as documented.

Before I raise with support, does anyone know of any reason why? It knows the client, as it does have the clientId - and if I look at this clientId in the dashboard it shows me the client mac!

Example response:

      "eventData": {
        "channel": "161",
        "rssi": "38"
      }
    },

I checked over a 24 hour period and all 3,000+ records all return with a null clientMac.

What's more strange is that the same clientMac field is correctly returned for the "disassociation" event type, so it appears limited to "association" only.

Thanks,

James

I would lean toward this being a Meraki backend defect or network-specific backend issue rather than a configuration problem. So, I suggets you open a support case.

+1 for opening a support case.
