Run resource booking approvals via delegated workflows

Intercept and route resource bookings—like rooms and equipment—through an approval workflow before confirmation, using a delegated service account.

The problem

Without intervention, any user with access can reserve a resource instantly, bypassing internal controls or policies. Some resources need oversight—like executive rooms or expensive equipment—yet Google Calendar’s built-in moderation is limited and inconsistent across resource types.

How it works

  1. Delegate a service account with domain-wide access to resource calendars.
  2. Monitor all incoming booking events on selected resource calendars.
  3. Intercept new bookings and place them in a pending state.
  4. Notify approvers and update the booking to confirmed or declined based on their response.

What changes

Resource bookings are consistently routed for approval, with a clear audit trail of who approved or rejected each request.

The trap in this one. Calendar API event updates are not atomic—if two bookings for the same resource overlap and approvals are processed in parallel, both may be accepted due to eventual consistency. This leads to double-booking unless you serialise approval decisions and re-read the resource’s current state before confirming any request.

Questions people ask

Can this handle recurring bookings or series?

It can, but you must handle each instance carefully. The Calendar API sometimes splits or merges series during updates, so track the series ID and all exceptions.

What happens if an approver doesn’t respond?

You can expire pending requests after a set time and notify the requester, but this must be enforced by your workflow, not the API.
