See Authentification. Use the access token as e.g. ACCESS_TOKEN .
Get the fob ID:
curl -X GET --header 'Accept: application/json' --header 'Authorization: Bearer ACCESS_TOKEN'
'https://api.nuki.io/smartlock/SMARTLOCK_ID/auth'
with fobs having 'type' : 2.

e.g. allow access from now on for all weekdays without further restrictions:
curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'Authorization: Bearer ACCESS_TOKEN' -d '{ \
"allowedFromDate": "2019-01-01T00:00Z", \
"allowedWeekDays": 124 \
}' 'https://api.nuki.io/smartlock/SMARTLOCK_ID/auth/KEY_ID'
To remove an allowedUntilDate again you have to set it to Null.
curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'Authorization: Bearer ACCESS_TOKEN' -d '{ \
"allowedUntilDate": Null \
}' 'https://api.nuki.io/smartlock/SMARTLOCK_ID/auth/KEY_ID'
