Set custom routes | Magento 2 Developer Documentation

You can configure REST endpoints in your module to use custom routes (aliases) for URLs instead of the default URLs. For example, you can define the alias createWidget to represent POST V1/widgets. However, you cannot create an alias for a route that contains one or more variables, such as PUT V1/widgets/:widgetId.

To define custom routes, create an etc/webapi_async.xml file in your module that contains the following structure:

<services xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_WebapiAsync:etc/webapi_async.xsd">
    <route url="V1/widgets" method="POST" alias="createWidget" />
    <route url="async/bulk/V1/widget" method="PUT" alias="asyncBulkUpdateWidgets"/>
    .........
</services>

This example redefines two routes:

All requests made on endpoint POST /createWidget will be forwarded to POST V1/widgets
All requests made on endpoint PUT /asyncBulkUpdateWidgets will be forwarded to PUT async/bulk/V1/widget

The following table defines the route node attributes:

Attribute name	Required	Description
`url`	Yes	An existing REST endpoint. The route can be defined in the module’s `webapi.xml` file, or derived, such as those for asynchronous and bulk endpoints.
`method`	Yes	The HTTP request method. One of `GET`, `PUT`, `POST` or `DELETE`.
`alias`	Yes	A string that defines the custom route for the route defined in `url`.
