# mergeContacts

Merge duplicate contacts into one survivor. contactIds: the full set (2+); primaryContactId MUST be one of them; it keeps its custom fields and agent, absorbing the others’ notes, tags, activities, campaign slots. name: its display name; optional pointPersonUserId picks the surviving agent. Returns the survivor. Losers are retired permanently: find them with findDuplicateContactGroups or findContacts. Delegate it with approvedIrreversible and bulkChange (count and contactIds: every contact merged; summary: the one kept); that card is the one yes.
