The problem

When staff leave or change roles, their vacation responders need to be set or cleared reliably, especially during holidays. Relying on users to do it themselves leads to missed or outdated auto-responses, and tracking status manually across hundreds of accounts is unworkable.

How it works

  1. Grant domain-wide delegation to a service account with the required Gmail settings scopes.
  2. Query each user's current vacation responder state using the Gmail API.
  3. Set or clear vacation responders as required based on roster or HR triggers.
  4. Log the actions for later audit and rollback if needed.

What changes

Vacation responders are reliably and quickly set or removed across all users, with a single source of truth and audit trail.

The trap in this one. The Gmail API's vacation responder settings endpoint is not idempotent: if you clear a responder and then immediately query, the old message may still appear for up to several minutes due to propagation lag. Scripts that check for successful removal by reading back the setting can falsely report failure or trigger retries, leading to unnecessary API calls and confusion. Always allow for propagation delay, and avoid tight read-after-write loops.

Questions people ask

Can we customise the responder message for each user?

Yes, the Gmail API allows setting a unique message per user. Maintain your templates and mapping in a Sheet or database, and apply them per account.

Is there an audit log of who changed what?

Not from Google directly for vacation responders. Keep your own log of changes made by the service account, including timestamps and user targets.

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.
