Notify users when shared documents are expiring in bulk

Scan shared Drive documents for upcoming expiry dates and notify each owner before access is revoked, at scale, using a delegated service account.

The problem

Documents with expiring external shares are easy to miss, leading to unexpected access loss or compliance gaps. Owners rarely track expiry dates themselves, especially at scale.

How it works

  1. Enumerate all shared documents in the target Drives using the service account.
  2. Read each file's permissions to identify those with upcoming expiry dates.
  3. Group files by owner and prepare notification emails summarising what will expire soon.
  4. Send notifications directly to each owner via Gmail API under delegation.

What changes

Owners receive regular, actionable warnings about documents that are about to lose shared access, reducing confusion and support tickets.

The trap in this one. Drive API's permission expiry field can lag behind reality: recently modified or bulk-updated permissions may not reflect their actual expiry until index propagation completes, leading to missed or duplicate notifications. Always re-scan after large permission changes to catch late updates.

Questions people ask

What if a document has multiple owners?

Notify all owners, but clarify in the message that action by any one of them will affect the shared link.

How often should notifications be sent?

Daily or weekly is typical, but frequency depends on document turnover and user expectations.

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.
