The problem

Staff turnover and organisational shifts mean contact details quickly become outdated. Relying on users to update their own contacts leads to inconsistency, and manual updates across hundreds or thousands of accounts are not feasible.

How it works

  1. Enumerate all user accounts using the Admin SDK.
  2. Impersonate each user in turn to access their contacts.
  3. Insert, update or remove contact entries as required.
  4. Log every change for audit and rollback purposes.

What changes

Contact lists are kept up to date for everyone, reducing misrouted mail and wasted time hunting for current details.

The trap in this one. The People API used for contact management enforces per-user write quotas and rate limits, but does not return a distinct error when limits are hit—writes simply stop applying, sometimes mid-batch, without an error at the API level. This leads to silent partial updates, where only a subset of users actually receive the changes, and the logs show no failures. Always verify with a second pass read after bulk updates, or you will not know which accounts are missing entries.

Questions people ask

Can I update contacts for suspended or archived users?

No. The API does not allow impersonation of suspended or archived accounts, so those will be skipped without notice.

Will these updates sync to mobile devices?

Yes, but only as fast as the user's device syncs contacts, which can introduce a delay of several hours.

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.
