# Webhook for updates to an existing utility account connection v2

> Fires when any field on a connection changes — status transitions, credential updates, account additions or removals, site reassignments, or other detail changes. Timestamp-only updates do not trigger this event. The payload includes `protectedChanges` (sensitive fields that changed) and `old` (previous field values).
