SalesChannel-API controller

This HowTo will give you a brief introduction on how to setup a custom SalesChannel-API controller with your plugin. Read here for more information about the SalesChannel-API. Also, this guide covers the same subject for the Admin API.

Plugin base class

You don't have to override any method in the plugin's base class for this subject.

<?php declare(strict_types=1);

namespace Swag\SalesChannelApiController;

use Shopware\Core\Framework\Plugin;

class SalesChannelApiController extends Plugin
{
}

Loading the controllers via routes.xml

The routes.xml file is necessary to introduce your controllers to Shopware 6. Shopware 6 automatically searches for an xml file in a src/Resources/config/ directory, whose path contains routes. Therefore possible default locations would be:

• /src/Resources/config/**routes**.xml
• /src/Resources/config/**routes**/my_controller.xml

Since only a single xml file is necessary for this example, the file is called routes.xml and will be put into the <plugin root>/src/Resources/config directory.

It only has to contain the path to the plugins controllers. This example will have its API controller inside a Controller folder.

<?xml version="1.0" encoding="UTF-8" ?>

<routes xmlns="http://symfony.com/schema/routing"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://symfony.com/schema/routing
        http://symfony.com/schema/routing/routing-1.0.xsd">

    <import resource="../../Controller" type="annotation" />
</routes>

The controller class

Next you create a directory src/Controller inside your plugin root and in there you create a new php file for your actual controller.

Here's an example of what the controller could then look like:

<?php declare(strict_types=1);

namespace Swag\SalesChannelApiController\Controller;

use Shopware\Core\Framework\Routing\Annotation\RouteScope;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\HttpFoundation\JsonResponse;

class MyController extends AbstractController
{
    /**
     * @RouteScope(scopes={"sales-channel-api"})
     * @Route("/sales-channel-api/v3/swag/my-sales-channel-api-action", name="sales-channel-api.action.swag.my-sales-channel-api-action", methods={"GET"})
     */
    public function myFirstApi(): JsonResponse
    {
        return new JsonResponse(['You successfully created your first SalesChannel-API controller route']);
    }
}

There are several things to note about the @Route annotation:

• In order for your controller to be an SalesChannel-API controller, your route needs to start with /sales-channel-api/
• The respective method only supports GET requests, hence the methods={"GET"} part of the annotation
• Make sure to use your vendor prefix (swag in this example), so route collisions with other plugins won't be an issue
