The problem

Manual room booking leads to double-bookings, missed releases and unused capacity. At scale, checking and updating room calendars by hand is error-prone and slow.

How it works

  1. Use a delegated service account with domain-wide delegation to impersonate users or a resource admin.
  2. Search for free/busy slots on room resource calendars using the Calendar API.
  3. Insert or cancel events programmatically, ensuring correct attendees and conference data.
  4. Send notifications or confirmations to organisers as needed.

What changes

Room calendars reflect real usage, bookings are consistent, and conflicts are handled programmatically without staff intervention.

The trap in this one. The Calendar API's event insertion is eventually consistent: a booking may not appear immediately when reading back free/busy times, especially under high automation load. This can lead to two automations believing they've booked the same slot, causing double-booking. Always re-read the room's calendar after insert with a short delay, and treat the booking as unconfirmed until verified.

Questions people ask

Can I impersonate a resource (room) directly?

Yes, you can impersonate the resource's calendar using its email address with domain-wide delegation, provided it is in your domain.

How do I handle recurring bookings?

Create recurring events via the API, but be aware that exceptions or changes can be slow to propagate. Re-read series for confirmation.

Want this built?

This is a pattern we run in production. We will set up the delegation and build this on top of it — $500 per hour, most of it working the same day.
