Work with reservations in Goki
Goki relies on PMSes to get the latest version of reservations as soon as they are created/updated in the PMS. We do not try to update any reservations directly on the PMS.
This is important to make sure only one system is reliable for that piece of information and in case of a mismatch, we always know we can rely on the PMS data and request a pull from the PMS.
In automating the check-in process, Goki calls the provided checkIn endpoint by PMS. It means PMS decides if the reservation status can change to checked-in or not. Once PMS checks the reservation in then it should send the reservation's update to Goki as normal.
