webapi.xml Reference Documentation
webapi.xml file in Magento 2 is a crucial configuration file that defines the web APIs available in your Magento
installation. This file allows you to control the access and behavior of your web APIs. In this reference documentation,
we will explore the structure and various elements of the
webapi.xml file, providing you with a comprehensive
understanding of how to utilize and customize web APIs in Magento 2.
webapi.xml file is located in the
etc directory of your Magento module. Its primary purpose is to define the web
APIs associated with that module. The file follows a hierarchical structure comprising of the following key elements:
Now, let's dive deeper into each of these elements and understand their roles in configuring web APIs.
routes element acts as the root element for defining the web API routes in your module. Under the
element, you define different routes that correspond to different parts of your module.
<routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Webapi:etc/webapi.xsd"><!-- Route definitions go here --></routes>
route element allows you to define a specific route within your module. Each route represents a specific URL
endpoint for accessing the web API. Within the
route element, you define the services associated with that route.
<route url="/V1" method="GET"><!-- Service definitions go here --></route>
In the above example, we have defined a route with the URL
/V1 and the HTTP method
GET. You can have
route elements within the
routes element, each representing a different URL endpoint.
service element represents a specific service or resource in your web API. It defines the URL endpoint for
accessing that service and also contains the methods associated with that service.

Magento\Catalog\Api\ProductRepositoryInterface and the
get. This service represents the product repository in the catalog API. You can have multiple
elements within a
route element, each representing a different service or resource.
