The duration, in seconds. The value can range from 900 seconds (15 minutes) up to 365 days. If value is higher than this setting, then operation fails. By default, the value is set to 3600 seconds. If no *DurationSeconds* is specified expiry seconds is obtained from *WebIdentityToken*.

| Params        | Value                                              |

However, if a request needs a certain identity that we have not fetched yet, it will be immediately requested.

Ztunnel additionally will handle the rotation of these certificates (typically 24hr expiration) as they approach expiry.
