In preparation for some upcoming backend v3 order api changes, we have separated orders into 2 different shapes: parent and child orders. See [https://devapiverson.docs.apiary.io/](https://devapiverson.docs.apiary.io/)

- The `/order/<order_number>` endpoint will always return the child order shape.
- The new `/order/parent/<parent_order_number>` endpoint returns the parent order shape.

#### Removed:

The v3 order shape no longer returns the `child_order_numbers` field. This information can be retrieved from the `/order/parent/<parent_order_number> [GET]` endpoint instead.  
Use the `parent_order_number` field from the v3 child order to construct the parent order’s url. The parent order contains information about all children orders.

#### Behavior Change:

When creating a new order via `/order [POST]` any configured automation rules will be applied and that could potentially split an order.  
The new behavior to tell when the order is “ready” is to poll `/order/parent/<parent_order_number> [GET]` and look for `ready=true`  
The parent endpoint will return all split orders in the `child_order_numbers` field.  
If no splits have occurred, then `child_order_numbers` will contain only 1 order number.
