Report on resource account usage across the domain

Track which meeting rooms or shared resources are actually booked and used, using a delegated service account for reliable reporting.

The problem

Resource accounts are often set up and forgotten, with little data on which rooms are booked but unused, or which resources are chronically overbooked. Manual audits are error-prone and quickly outdated.

How it works

  1. Use the Admin SDK to enumerate all calendar resource accounts in the domain.
  2. Delegate a service account with calendar.readonly scope to each resource account.
  3. Query the Calendar API for each resource to pull event history and no-show patterns.
  4. Aggregate and export the usage data for reporting and operational review.

What changes

Facilities and IT can make evidence-based decisions on resource allocations, and spot under-used or over-subscribed assets across all locations.

The trap in this one. Calendar API event feeds for resource accounts can lag actual booking changes by several minutes, especially for large domains or recently modified events. If you query immediately after a booking is created, modified, or cancelled, the results may not yet reflect the true state, leading to under- or over-reporting on usage unless you account for this propagation delay.

Questions people ask

Do I need to grant full calendar access?

Read-only access is sufficient for usage reporting, and reduces risk if the credentials are misused.

How do I identify which accounts are resource calendars?

The Admin SDK's resources API lists all resource calendars, including their email addresses and metadata.

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.
