What is eCommerce API?

eCommerce APIs are used by developers for transferring the specific info from one software to another one. For example, when the B2B software providers who work with e-retailers need to access the data from particular shopping platforms, they need to develop the API integration with them.

API or Application Programming Interface acts as an intermediary between various digital products and applications. The API works as a messenger. It delivers a particular request to the other app and then comes back with the answer.

API request happens when the developer adds the endpoint to the URL and performs a call to the server. The API response is received after the making of the API request. Usually, it can be in XML or JSON format.

eCommerce API integration means the process of tying the various software solutions or applications with the purpose of sharing the data between them. API integration allows software developers to get access to all the needed data from the required solution and manage it by their systems.

The development of the eCommerce API integration with shopping platforms like Magento, Shopify, OpenCart, PrestaShop, WooCommerce, WP e-Commerce, etc. requires high-quality specialists, previous investigations, a lot of time and further maintenance and upgrading. It is a technically complex process that can cost thousands of dollars if performed in-house. That is why more and more B2B software solutions choose to use third-party services for the development of API integration as they can help them to save their money and time.

More detailed info about the eCommerce API and eCommerce API integration development you can find in the infographic below.


Most Popular eCommerce APIs of 2022

The most popular eCommerce APIs list includes Magento API, Shopify API, Ecwid API, WooCommerce API, Amazon API, eBay API, Etsy API. Let's explore them in detail.

Magento API allows developers to access the needed data from Magento stores. Magento supports REST and SOAP APIs. Performing requests and receiving the responses are possible with the help of using the HTTP protocol.

Shopify API also enables developers to retrieve the data from Shopify stores. It supports XML and JSON formats. Shopify API works with HTTP requests (GET, POST, PUT, DELETE).

Ecwid API is a REST API. It allows developers to easily read, create, update, and delete Ecwid store data. For example, such data includes store categories, products, orders, coupons, etc.

WooCommerce API is a REST API that allows creating, reading, updating, and deleting WooCommerce data. It supports JSON format.

The Amazon API provides a set of tools to access and manipulate data related to listings, products, payments, and more. It also lets you retrieve reviews and seller information. The API only supports CSV files or XML for communication, so it requires some programming knowledge to use.

eBay's API is widely used. However, it has its unique features. eBay's data formats are not uniform; various resources like products, customers, and orders have different data formats. eBay's API documentation does not always provide the answers to developers' questions. Most often, these answers are found in forums on the eBay Developers site.

The Etsy eCommerce API for developers enables them to read and write data from stores via a RESTful interface while using lightweight JSON formatted entities. The Etsy API's OAuth method enables authentication of users, after which developers are able to use the GET (reads a resource), POST (creates a new resource), PUT (updates a resource), and DELETE (deletes a resource) methods for output.
