We are interested on using Catalyst Center "clients" API (/dna/data/api/v1/clients) for getting information about clients associated to a connected Wireless Controller. The API may take between 30 seconds and 4 minutes to show changes. Could you give some insight on the reason for this variability? Can this timing be adjusted to a shorter refresh period?
Thank you very much in advance,

This is unfortunately not something you can change, if you need real time data you will need to fetch it directly from your WLC.

Thank you very much. What would be the equivalent to fecht client information from the WLC (C9800-40-K9)?

You would probably want to use SNMP, netconf or restconf for this. MDT over gRPC is also an option if you want to go down that route. For Netconf/Restconf this is the module you want to use: https://github.com/YangModels/yang/blob/main/vendor/cisco/xe/1791/Cisco-IOS-XE-wireless-client-oper.yang

Catalyst Center provides client assurance data, wireless or wired, aggregated for the past 5 minutes. The same data and user experience is when using the UI or API. Depending when you make the API call you may receive few minutes old collected data, depending when it was collected last from the device - switch or controller. This is not something you may configure.
