Beim Buchen eines Termins muss zuerst die Lease erstellt werden. Das Back-End des Partners prüft, ob der angeforderte Slot gültig und noch verfügbar ist. Intern erstellt der Partner einen temporären Hold für den angeforderten Slot, der automatisch um lease_expiration_time abläuft. Das Back-End darf lease_expiration_time ändern, z. B. wenn die angeforderte Zeit für die Lease zu lang ist. Die erstellte Lease wird an den Client zurückgegeben.
