We recommend pairing Robin with a generic booking ("service") account instead of a personal one. Something like email@example.com or firstname.lastname@example.org. Once your organization has a booking account connected, you can enable user impersonation to make sure everyone signing in via Google can book directly as themselves when possible.
If your company already uses a generic booking account to manage your meeting rooms, then that's what you'll want to pair with Robin.
If not, we recommend that the administrator for your company's G Suite for Business create a user account to manage bookings for Robin.
Why use a dedicated booking account?
Think of this as the invisible booking assistant for your office. Any anonymous calendar invitations will come from this account, and any events booked through Robin that can't be created on behalf of the user will show up on calendars owned by this account. Adding a booking account keeps your personal calendar clear of other folk's events. Make sure to give it the right permissions to avoid conflicts.
Here's an example calendar event booked through Robin. Hal is the generic booking user for our team.
Create Google resource calendars for each of the rooms you'll add to Robin.
