Does anyone know if there there is any API that allows to connect to the Integrated WLC on the Aironet 1830, 1850, 2800 or 3800 Series APs? If there is can you please provide a link to it?
As far as I know the API only exists on Cisco Prime Infrastructure so you would need to install that to poll your AP/WLCs via SNMP and then do your GET requests.
