This post covers

Let’s explore the Magento 2 API.

Introduction to Magento 2 API

Application Programming Interface (API) is a software intermediary that facilitates data flow between two applications/system through a standard protocol. Near to perfect metaphor of API can be a common language of communication between two people coming from different locations.

Magento 2 (Adobe Commerce) offers built-in API, which can let other applications use Magento’s functionalities and interact with the platform.

By default, Magento 2 supports three types of API:

  • Representational State Transfer (REST) – RESTful API communicates over the internet via HTTP.
  • Simple Object Access Protocol (SOAP) – It is a protocol that relies on XML files for exchanging data.
  • GraphQL – Data-query language used by Magento 2 for frontend development.

In order to use the API in Magento 2, you need to register a new web service, create a new integration, and configure the authentication. You can follow these simple steps to do that:

  • Create a New Web Service: Go to System > Permission > All Users > Add New User and create a new token-based authentication in Magento 2.
  • Create a New Integration: Go to Systems > Extensions > Integration > Add New Integration to do that.
  • Configure Authentication: Set up the authentication via REST or SOAP per your needs.

Magento 2 REST API is the widely used for integration and application development relies significantly on the secure implementation of Magento 2 API keys. In this post, we’ll focus primarily on the RESTful API in Magento 2.

REST API in Magento 2

The Magento 2 REST API help use the features outside the platform.

You can use all the frontend and backend functions of Magento 2 by calling the REST API endpoints. These requests use three types of authentication, namely:

  • Token-Based Authentication: Uses tokens generated using username and password to authenticate the requests.
  • Session-Based Authentication: Uses Session ID generated by the server for request authentication.
  • OAuth-Based Authentication: Uses Authorization Tokens to validate the API requests.

Now, the Magento 2 REST API endpoints can also be categorized based on the type of user:

  • Guest User: Public API endpoints that require no authentication. (For e.g. get product information)
  • Admin User: Private API endpoints that require admin-level access. (For e.g. change product information)
  • Customer: Private API endpoints that require customer-level access. (For e.g. view previous orders)

Based on the type of operation, you may require sending the authorization token in the Magento REST API request for authentication. You can also develop your own custom API in Magento 2 and use it!
