data shape.
Order event money fields are sent as decimal major currency units for most currencies. For example, Singapore dollars are sent as dollars, not cents.
Event types
Payload
cart_id is the cart the order was created from. It is null when the order has no cart. It equals id on cart events for the same visit, so both event streams resolve to one check.
order_items contains top-level items only.
sub_items contains modifiers and nested components attached to a parent item. A sub-item uses the same fields as a top-level order item. The order_item_id field points to the parent order item, and modifier_id is present when the sub-item came from a modifier.
