Magento 2 API, Page 4 Category

To Get products list Through Magento 2 REST API is not a big deal when you develop any native application. Here I am going to explain how we can get all the products list using Magento 2 REST API.

Wishuscess_ProductList is a complete module that helps you to decide a custom web API route id and that route id we will use to call this Wishuscess_ProductList on the postman server to test our custom REST API to get the product list.

Magento 2 REST API TO GET Products List

Here we have to create two classes one is the product list interface and the second is the model product list repository which helps us to get the complete product list through API calls.

app/code/Wishusucess/ProductsList/registration.php

app/code/Wishusucess/ProductsList/etc/module.xml

app/code/Wishusucess/ProductsList/etc/di.xml

app/code/Wishusucess/ProductsList/etc/webapi.xml

app/code/Wishusucess/ProductsList/Api/ProductListInterface.php

app/code/Wishusucess/ProductsList/Model/ProductListRepository.php

Create Magento 2 Rest API GetProductsList

You have to create a separate module for it so then you can decide the rest web API route id and then that web API you have to call on your different server to get the product list data.

Step 1: Registration

app/code/Wishusucess/ProductsList/registration.php

<?php
/**
*
* Developer: Hemant Singh Magento 2x Developer
* Category: Wishusucess_ProductsList
* Website: http://www.wishusucess.com/
*/
\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'Wishusucess_ProductsList',
__DIR__
);

Step 2: Module Information

app/code/Wishusucess/ProductsList/etc/module.xml

<?xml version="1.0"?>
<!--
/**
*
* Developer: Hemant Singh Magento 2x Developer
* Category: Wishusucess_Customer
* Website: http://www.wishusucess.com/
*/
-->
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
<module name="Wishusucess_ProductsList" setup_version="1.0.0" />
</config>

Step 3: Dependency Injection

app/code/Wishusucess/ProductsList/etc/di.xml

<?xml version="1.0"?>
<!--
/**
*
* Developer: Hemant Singh Magento 2x Developer
* Category: Wishusucess_Customer
* Website: http://www.wishusucess.com/
*/
-->
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="Wishusucess\ProductsList\Api\ProductListInterface" type="Wishusucess\ProductsList\Model\ProductListRepository" />
</config>

Step 4: Create Route ID To GET Products List

app/code/Wishusucess/ProductsList/etc/webapi.xml

<?xml version="1.0"?>
<!--
/**
*
* Developer: Hemant Singh Magento 2x Developer
* Category: Wishusucess_Customer
* Website: http://www.wishusucess.com/
*/
-->
<routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Webapi:etc/webapi.xsd">
<route url="/V1/wishusucess/products" method="GET">
<service class="Wishusucess\ProductsList\Api\ProductListInterface" method="getList"/>
<resources>
<resource ref="Magento_Catalog::products"/>
</resources>
</route>
</routes>

Step 5: Create Model Repository Class

By using this repository class you will decide how you are going to receive or process the request. Suppose you are getting a request to give the product list based on the SKUs then you have to decide all those parameters here.

Here you can set the product links as well in all those products with cache images and we have also added a function to get the product based on the product by id so when you will hit the API with product id then you will get the result.

app/code/Wishusucess/ProductsList/Model/ProductListRepository.php

Step 6: API Class GET Products List Interface

So, here you have to create a function getList() that will have some search criteria as a parameter and when you will give that parameter and then send a request then Magento 2 will ask you to authorize first so you have to send with an admin token then Magento 2 website will give you the products list.

app/code/Wishusucess/ProductsList/Api/ProductListInterface.php

<?php
/**
*
* Developer: Hemant Singh Magento 2x Developer
* Category: Wishusucess_Customer
* Website: http://www.wishusucess.com/
*/
namespace Wishusucess\ProductsList\Api;
/**
* @api
*/
interface ProductListInterface
{
/**
* Get product list
*
* @param \Magento\Framework\Api\SearchCriteriaInterface $searchCriteria
* @return \Magento\Catalog\Api\Data\ProductSearchResultsInterface
*/
public function getList(\Magento\Framework\Api\SearchCriteriaInterface $searchCriteria);
}

Now, Run The Following command:

php bin/magento s:up

php bin/magento s:s:d -f

php bin/magento c:c

Now, we have created our Magento 2 product list rest API, so in order to use this API we have to create an admin token first then we have to use that token and send the request in the below format.

https://www.wishusucess.com/rest/store_id/V1/wishusucess/products

With Get method when you will send the request in above format of URL then you will get the product list data.
