Sync external contacts to the company directory

Push external partner and customer contacts into the Workspace directory so staff autofill and sharing work as expected.

Who it is forIT admins and operations teams responsible for maintaining up-to-date shared contacts.

The problem

Manually updating directory contacts is slow and inconsistent, so users can't reliably find external partners or customers by name. Missed updates mean bounced emails or accidental use of personal address books.

How it works

  1. Aggregate the authoritative list of external contacts from your CRM or HRIS.
  2. Transform the data to match the schema expected by the Admin SDK's Directory API.
  3. Use a delegated service account to batch upserts of these contacts into the domain directory.
  4. Regularly reconcile the directory to detect and remove stale or orphaned entries.

What changes

All staff see the same, current list of external contacts in Gmail, Calendar and Drive, with correct names and addresses.

The trap in this one. The Admin SDK's contact insert and update endpoints are not fully idempotent: submitting the same external contact multiple times can silently create duplicates if the resourceId is not tracked and reused. If your sync does not persist and re-use Google's generated IDs, re-runs lead to a polluted directory that users cannot clean up from the UI.

Questions people ask

Can you restrict who sees these contacts?

No — directory contacts are globally visible to all users in the domain. There is no per-user or per-group visibility control.

How fast do changes propagate?

Expect up to several hours before updates are reflected in autocomplete and sharing dialogs, as client caches and directory indices update on their own schedule.
