I've created a couple of order attributes using the method described here (https://www.yereone.com/blog/magento-2-how-to-add-new-order-attribute/) in order to save some data that is passed into Magento 2 via our legacy application.

Is it possible to pass these values over when creating an order via the API? or is there a better way to achieve the same result? I'm using Magento 2.3 if that has any impact.

First read this below articles:

• https://store.fooman.co.nz/blog/an-introduction-to-extension-attributes.html


• https://devdocs.magento.com/guides/v2.3/extension-dev-guide/extension_attributes/adding-attributes.html

If you want to add a field them you need to use extension_atttibutes

Extension attribute gives the facility to add a new field to existing API point.

The fields which you have created using https://www.yereone.com/blog/magento-2-how-to-add-new-order-attribute/) to be used as an extension attribute for data MagentoSalesApiDataOrderInterface.

So, create etc/extension_attributes.xml at your module folder

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Api/etc/extension_attributes.xsd">
 <extension_attributes for="MagentoSalesApiDataOrderInterface">
 <attribute code="is_important" type="string" /> <!-- type defined as string -->
 </extension_attributes>
</config>

Save field to order table

And as you have created the column to an existing order table, So save the create before plugin on MagentoSalesApiOrderRepositoryInterface::save().

<?php

namespace YereoneNewOrderAttributePlugin;

use MagentoFrameworkExceptionCouldNotSaveException;

class OrderSave


...

 public function beforeSave(
 MagentoSalesApiOrderRepositoryInterface $subject,
 MagentoSalesApiDataOrderInterface $resultOrder
 ) 

 $extensionAttributes = $resultOrder->getExtensionAttributes();
 if (null !== $extensionAttributes) 
 $extensionAttributes->getIsImportant()->getValue();
 $resultOrder->setIsImportant( $extensionAttributes->getIsImportant()->getValue()); 
 
 return $resultOrder;
