Hi,
yes this is easy possible, in your configuration.php you can adjust the "fusio_expire_token" setting, by default it is "P2D" which means, that the token expires in 2 days. You can adjust this to i.e. "P1D" for one day or "PT6H" for 6 hours,
the "expires_in" time is a UNIX timestamp in seconds.
best regards
Christoph
