Orders without Order Items, with 0 total money amount

Questions

I’m seeing a TON of orders with no order items (), and total_money_amount = 0. Is it possible for retailers to create empty orders? why would that happen?

Here’s an anon example:
{"id": "asdkfljksdfjkdjf", "line_items": [], "updated_at": "2019-09-07T20:53:57Z", "location_id": "dsfkladslfasdjfj", "total_money": {"amount": 0, "currency": "USD"}, "total_tax_money": {"amount": 0, "currency": "USD"}, "total_discount_money": {"amount": 0, "currency": "USD"}, "total_service_charge_money": {"amount": 0, "currency": "USD"}}

With the Orders API you can create an order with as little as an idemopotency_key and a location_id. Depending on the use case there may be many reasons you would want to first create the order and update it with [UpdateOder](https://developer.squareup.com/reference/square/orders-api/update-order) throughout the lifecycle of the order.
