is this possible in Magento 2 and how can I write a plugin using di.xml which only call when request form API

Any idea? any help appreciate

Answer 1

You need to create plugin in di.xml inside etc/webapi_rest folder to call plugin only in REST API.

Example :

app/code/Vendor/Module/etc/webapi_rest/di.xml :

<?xml version="1.0"?>
<!--
/**

 * See COPYING.txt for license details.
 */
-->

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<type name="Magento\Catalog\Api\ProductCustomOptionRepositoryInterface">
        <plugin name="updateProductCustomOptionsAttributes" type="Magento\Catalog\Plugin\Model\Product\Option\UpdateProductCustomOptionsAttributes"/>
    </type>
</config>

Add your plugin based on your requirement in di.xml.

Answer 2

It should be app/code/Vendor/Module/etc/webapi_rest/di.xml
