    Key Features

    • User-Level Authentication: Enables the creation and management of reservations on Google Calendar.
    • Reservation Restrictions: Specific limitations apply when creating, updating, or deleting reservations under personal authentication mode.
    • Integration Behavior: Reservations created through non-ServiceNow interfaces are placed in the delegated user's mailbox.

    Key Outcomes

    With a personal authentication mode connection, you will be able to:

    • Synchronize reservations effectively while adhering to the established restrictions.
    • Create blocker and on-behalf reservations only where permitted (i.e., non-synchronized rooms).
    • Understand the limitations on updating or canceling reservations, ensuring proper management of calendar events.

    This setup enhances the control and flexibility of managing Google Calendar reservations while ensuring compliance with the specified restrictions.

    Blocker reservations When Personal mode is enabled, blocker reservations are created in the delegated user's calendar, with the requested for user added as an invitee.

    Onbehalf user reservation The This reservation is for field is not displayed in personal authentication mode. In personal mode, you can't create Onbehalf user reservations because you don’t have access to other user's calendar. However, you can create on-behalf reservations for non-synchronized rooms.
    Group reservations Group reservations aren’t supported in Personal mode for synchronize-enabled rooms, even if the Enable group reservations check box is selected in the reservable module. You can create group reservations for non-synced rooms.

    • If the Sync mailbox is set to user, the following rules apply:
      • If the reservation is edited or canceled from sources other than WSD Portal, Quick Reservation, WSD Mobile, or Event Planner, it can’t be updated or canceled.
      • If the session user (the person who is updating or canceling the reservation) doesn’t match the requested-for user, the reservation can’t be edited or canceled.
      • If a personal token doesn’t exist for the user updating or canceling the reservation, the reservation can’t be updated or canceled.
      • In all other cases, the reservation can be updated or canceled.
