On behalf of the user, we will visit the reservation site of the registered tennis facility and check the availability of the court. Once we have found a court that meets your criteria, we will use your account to make a reservation. Reservation results will be notified by email and push notification. In order to make a reservation, it is necessary to deposit a reservation account and password and set reservation rules in advance. If the found empty court matches the reservation rules from multiple users, an automatic lottery will be performed.
