Previously the response was mistakenly a `200` with no body content. 😞 - [Retrieve an Order](https://developer.infusionsoft.com/docs/rest/#!/E-Commerce/searchUsingGET): Can now return orders that have no order items. Previously the endpoint acted like item-less orders did not exist. 😞 - [List Orders](https://developer.infusionsoft.com/docs/rest/#!/E-Commerce/searchUsingGET): Now includes orders that have no order items. Previously the response did not include item-less orders. πŸ€·β€β™‚οΈ ---
