      "userToLinkId": "64b7f2b3e4b0a5d3f9c54321"
    }
  }'

Notes

  • This is an admin-only endpoint - requires administrative privileges
  • Both user IDs must be valid MongoDB ObjectIds
  • The secondary account (userToLinkId) will be permanently deleted
  • All linked accounts from the secondary user are merged into the primary
  • This action is irreversible - the secondary account cannot be restored
  • Use this to consolidate duplicate user accounts
  • The primary user retains their original ID and all merged linked accounts
  • Permissions and department assignments from the secondary account are lost
