Bulk manage contacts for user groups with delegation

Add, update, or remove contacts across entire user groups using a delegated service account, avoiding manual repetition.

Who it is forWorkspace admins managing shared contacts or address books for multiple teams.

The problem

Manually updating contacts for every user in a group is slow and error-prone, especially when organisational structures or external partners change. Delegated automation promises consistency, but group-based contact management is not natively exposed.

How it works

  1. Enumerate all users within the target group using the Admin SDK.
  2. For each user, impersonate via the delegated service account.
  3. Perform contact add, update, or removal operations per user.
  4. Log actions and confirm successful changes for traceability.

What changes

Contacts are reliably managed across all users in specific groups, with less manual effort and fewer missed updates.

The trap in this one. The People API enforces per-user write quotas and rate limits, and these are not reset by re-authenticating as the same user via delegation. Bulk jobs that ignore these limits will silently skip updates or return 429 errors mid-run, leaving group members out of sync. Retrying without logging which users failed leads to inconsistent address books and hard-to-diagnose support calls.

Questions people ask

Can I push a contact to all group members at once?

No. There is no group-wide contacts object; you must update each user individually via delegation.

How do I avoid rate limiting?

Batch updates with throttling, respect the documented write quotas, and persist user-level statuses so retries only target failed accounts.

Want this built?

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.
