Grant and revoke document access on a schedule

Automate temporary sharing of Drive files by time window, using a delegated service account to apply and remove permissions.

The problem

Manual sharing and unsharing is unreliable and often forgotten, risking prolonged exposure of sensitive documents. Automating time-bound access ensures compliance and limits liability, but requires precise control and tracking.

How it works

  1. Store the list of users, documents, and access windows in a durable source like a Sheet or database.
  2. At the start of the window, use the delegated service account to grant the specified permissions via the Drive API.
  3. At the end of the window, revoke permissions for each user on each document.
  4. Log every change with a timestamp, user, and document ID for audit.
  5. Alert if any grant or revoke operation fails or returns unexpected results.

What changes

Access to sensitive documents is tightly constrained to the intended window, with auditable logs showing exactly who had access and when.

The trap in this one. Drive API permission changes are not always instantly reflected: revokes can lag by several minutes, especially on shared drives or large folders, leaving a window where users retain unintended access. Always account for propagation delay and never assume immediate enforcement—schedule revokes slightly before the true cut-off and verify with a separate fetch-permissions call.

Questions people ask

How do I handle users who are offline when access expires?

Revoking Drive permissions prevents new access attempts, but cached copies can persist if a user had the file open. For highly sensitive content, avoid 'Editor' grants and use View-only links with download/export disabled.

What if a revoke fails for a user?

Retry with exponential backoff and alert on persistent errors. Check for changes in the user's account status or document ownership that could block the API call.
