# Purchase order numbers added to Orders/DraftOrders object

As of API version **2023-07** we have added a new field called `poNumber` to the `Order` and `DraftOrder` object.

The `OrderInput` and `DraftOrderInput` input objects now accept a `poNumber`. This will set the purchase order number during an `orderUpdate` , `draftOrderUpdate` and `draftOrderCreate` mutation.
