How to get Captive Portal users' expiration date using API?

[Marc_Abaya]

We're using Captive Portal/Splash Login to authenticate our WIFI users. Our time period is 30 days and they need to sign-in again. 

Just curious if there's a way to capture the users' expiration date via API? Our goal is to notify the users a day before their expiration date. I tried getNetworkClients but the expiration dates aren't showing there. Thanks in advance.

Take a look at this API.

Sorry I forgot to mention we're using Google OAuth for the sign-in: 

The /merakiAuthUsers request didn't show any results.

So, it's no possible.

Meraki does not expose expiration dates for users authenticated via Google OAuth through the Dashboard API.

I would look in Network-Wide/Events, and find an event that relates to a user logging in.  Note the info in it.

Then, in your script, retrieve just these kinds of events from the event log.  Note the time of the most recent login and check if it is close to 30 days ago.
