Integrating Magento 2 REST API: Developer's Guide

As a strong e-commerce platform, Magento supports brands ranging from sportswear's Helly Hansen to automotive giants like Ford and Land Rover. Magento 2 (Adobe e-commerce) improves Magento 1's security features and scalability and offers an easy-to-use administrative interface.

In terms of APIs, Magento 1 REST API and Magento 2 REST API have some key differences. Magento 2 REST API streamlines and smooths REST requests, making the process of third-party integration easier and more flexible.

Here are some of the key benefits of Magento 2's REST API for e-commerce store developers, managers, and administrators:

Working With Products and Magento 2

There are three significant ways the Magento 2 API helps developers work with store products. First, admins and developers can sync product catalogs with business ERP systems across the enterprise. When products are out of stock or on backorder, the API can modify the store automatically.

If your store is heavy on product data, Magento REST API enables integration with product information systems, letting your enterprise automate and streamline the product information and updating process.

 

Magento 2 Create Product REST API

The "Create Product" REST API supports adding a variety of products to the storefront and across third-party platforms. Using this REST API, Magento enables you to add a simple product, a virtual product, product bundles, downloads, and product groups in an automated process.

It's a completely customizable process, and it also lets you validate data to comply with various standards for product identifiers, quantities, sales data, cross-border shipping, and more. Here are some key fields that you can use in creating products using this type of API request:

SKU
Name
attribute_set_id
Price
Status
Visibility
type_id
weight
[Custom attributes as needed]

The process can be completely secure: as a developer/administrator, you authorize users who can add or modify products using the create product REST API.

The REST API for Magento also enables improved product management processes through dynamic attribute management. And, you can customize product types, giving you the flexibility you need to modify the storefront and continue to maintain functionality without making unnecessary changes to the underlying database.

Product Recommendations Using Magento 2 Custom REST API

There are few e-commerce stores that don't want to implement personalized product recommendations. Magento 2 Custom REST API allows you to do this by using endpoint definitions and business logic (including algorithms and machine learning models).

You can successfully integrate collaborative filtering programs and content-based filtering using the custom REST API in Magento, and also integrate customer segmentation models, including K-Means clustering and hierarchical clustering.

Here's how this can work using Magento 2 REST API endpoints:

  • Define an endpoint, like '/rest/V1/custom/recommendations/{customerId}'.
  • Integrate the ML model or similar customer segmentation engine.
  • Use the API to return a list of recommended products showing the product, price, and image.

The more effective the filtering or segmentation model is, the better results you may see in your store from repeat purchases, upselling, and higher customer retention.

Working With Orders and Magento 2

Magento 2 REST API supports automated order processing, which can greatly reduce order processing times. You can also cut down and even potentially eliminate manual order processing with smooth-running integrations. You can also automate order workflows, delivering timely updates along with more efficient processing.

Post-purchase customer support becomes easy with Magento 2, offering real-time updates on order status and shipment tracking information.

Magento 2 REST API Working With Customers

You can perform bulk updates of customer information with Magento 2 REST API. Marketing departments will appreciate the insights provided by the platform, including detailed, actionable insights into customer preferences, behavior, and trends. Finance and marketing departments will also appreciate the platform's capacity for customized reports on CAC costs, customer retention, and lifetime customer value (LTV).

As your store or store network grows, Magento REST API will also support efficient management of growth and scalability. You can customize the API to support behaviors of various customer profiles or integrations with their desired third-party platforms.

Security is also improved, with the ability to provide controlled access to customer information and extremely secure transactions, robust encryption, as well as the ability to adhere to global data protection regulations.

Magento 2 REST API Inventory Management

Get the dynamic, accurate stock management you need with Magento's API. The platform easily automates the process of updating stock when orders are placed, shipped, or returned. It will also synchronize across channels, eliminating problems with updates related to purchases made via third-party platforms or sellers.

The API will support bulk updates for product stock and availability, and will also do scheduled updates at intervals you choose.

Using Magento 2 Extension Attributes REST API

Admins and developers can use extension attributes through Magento 2 to add and change customized attributes throughout a store, including orders, customers, and products. The Extension Attributes REST API provides powerful additional flexibility without directly modifying the underlying database for your store.

The process for using extension attributes is simple, too:

First, define extension attributes using the extension_attributes.xml file. You will need to create this file first before modifying it.

Then, you'll need to implement getters and setters in your data interface.

Once this process is complete, you can manage the process. You can create or update entities (whether products or customers) that have extension attributes using POST requests or JSON.

Other benefits of using Magento 2 Extension attributes include backward compatibility, which will retain the information during future upgrades. You can also provide custom logic in the instructions, allowing you to have fine-grained control.

Here's one example of an ideal use for Magento 2 Extension attributes: product warranties. You can attach warranties to every product in your catalog that needs one to be delivered to purchasers.

First, you would define the warranty as an extension attribute. For example, add 'manufacturer_warranty' as an extension. Update the product entity by including 'manufacturer_warranty' in the payload when you create or update the product.

Handling Magento 2 REST API Authentication

Magento 2 REST API authentication uses a token system, with admin tokens providing authentication for administrator-level processes, and customer tokens supporting access to customer-level processes. It's simple and secure to use both levels of authentication for store management purposes. Token headers also appear throughout subsequent API requests.

Here's a Magento 2 REST API authentication example which will result in an admin token:

Send a POST request to '/rest/V1/integration/admin/token' with your admin user's username and password:

POST /rest/V1/integration/admin/token
Content-Type: application/json
{
"username": "your_admin_username",
"password": "your_admin_password"
}

JSON response will be "your_admin_token_here".

You can then use the admin token to access admin endpoints. Follow a similar process to request and receive an authenticated customer token.

Doing CRUD Operations And Using Magento 2 REST API Documentation

There are two ways to access Magento 2 REST API documentation. First, you can use your own site's URL followed by '/swagger'. Second, you can access the official Magento REST API documentation by using Adobe's DevDocs site.

Doing CRUD Operations And Using Magento 2 REST API Documentation

There are two ways to access Magento 2 REST API documentation. First, you can use your own site's URL followed by '/swagger'. Second, you can access the official Magento REST API documentation by using Adobe's DevDocs site.

located at https://developer.adobe.com/commerce/webapi/rest/quick-reference/

When you're working with the documentation, you'll notice that it's divided into API endpoint sections that correspond with the different functions of your e-commerce site, including customers, orders, and products. Then, it divides instructions by CRUD operations, with sections for create, read, update, and delete.

The documentation instructs you according to endpoint detail following this structure:

  • Path to endpoint
  • HTTP method (POST, GET, DELETE, PUT)
  • Parameters: query parameters, both required and optional
  • Responses: examples, status codes, and response bodies

Before using the documentation to interact with the API, you'll need to obtain admin or customer tokens, as Magento's API functions using token-based authentication.

Useful Integrations With Magento 2 REST API

Magento's current REST API supports the functions that e-commerce developers and administrators need to have to support robust e-commerce programs and integration with enterprises. It can support:

  • CRM integration
  • ERP integration
  • Data synchronization
  • Reducing manual data entry

Benefits of Magento's REST API For Developers
