If, as a FrankieOne Customer, you are acting on behalf of your own customers, then you can populate this field with a FrankieOne-assigned ID.
Note: If using a CustomerChildID, you will also need a separate api_key for each child.
Any documents, checks, entities that are created when this field has been populated will now be tied to this CustomerID + CustomerChildID combination. Just as Customers cannot see data created by other Customers, so too a Customer’s Children will not be able to see each other’s data.
A Customer can see the documents/entities and checks of all their Children.
