how shopping cart API works

Shopping cart API integration is the process of establishing a connection between an app or software and an eCommerce platform. As a consequence, software providers can offer various useful features for online store owners. It involves order management, inventory sync, product management, and many more.

If you have already developed an integration with shopping carts, you may know that its implementation involves a lot of challenges. Let's explore some of them below.

Shopping Cart API Examples

Each shopping cart API has its own logic and specifics. Let's see some examples of popular eCommerce APIs:

  • Magento API

It allows developers to get access to online stores built on the Magento platform and manage data like customers, orders, products, etc. The API supports both REST and SOAP communication protocols. The REST API provides a set of functions that you can use to send requests and receive responses using the HTTP protocol. Namely, by using GET, POST, PUT, or DELETE methods, you can work with Magento data according to your business needs.

  • WooCommerce API

This API enables developers to read, create, update, and delete data from WooCommerce stores, like products, prices, orders, customers, and shipping statuses.

  • Shopify API

It allows software providers to access data from Shopify-based eCommerce stores and use it for their own business goals. The API supports XML and JSON formats and can be accessed via HTTP requests such as GET, POST, PUT, and DELETE.

  • BigCommerce API

BigCommerce's RESTful API makes it easier to integrate your applications with BigCommerce and lets you code in the language of your choice. It allows one to get and manage such store data as orders, products, customers, categories, shipments, and other store info. The API supports all CRUD actions through HTTP methods (GET, POST, PUT, DELETE).

  • Squarespace API

This shopping cart's API includes Inventory API, Orders API, Products API, Profiles API, Transactions API, and Webhook Subscriptions API. They enable developers to access stock information, retrieve order history, get and manage products, etc.

Which Industries Need Shopping Cart API Integration

A lot of industries rely on shopping cart API integration for their success. Below are some of them.

eCommerce Marketing Automation Software

Marketing automation software relies on integration with shopping platforms for a number of reasons: to access data about products and orders, customer contacts, coupons, etc.

In many marketing automation processes, information from e-stores is a central component. Shopping cart integration enables systems like these to send emails with new items, discounts, and special prices to online stores' customers, notify them of order statuses, track cart abandoners, and generate smart email statistics.

Multi-Channel Software

For such systems, a seamless shopping cart API connection is a necessity. It allows them to get info on products, orders, shipments, inventory levels, etc., and update the data across all sales channels.

Shipping Management Software

Shipping software depends greatly on integration with shopping carts, which allows them to get orders from various sales channels, update tracking info and order statuses, create shipping labels, and organize the data in detailed reports.


To build an eCommerce chatbot, it must be integrated with the business ecosystem (shopping carts, in the first place) in order to access product catalogues, data on inventory levels and tracking numbers, etc. The system needs to be able to handle orders, change stock levels, and get lists of abandoned orders. For this to happen, it must connect with dozens of different shopping cart APIs.

What are the Main Pitfalls of Shopping Cart Integration?

Different eCommerce software for online retailers is mainly driven by integration with shopping carts to deliver their functions and products. For instance, shipping software requires integration to enable retailers to import orders and update order status.

Shopping cart API integration is a completely necessary investment for every provider of eCommerce software. There is, however, little awareness among many eCommerce software providers about how much commitment it takes to develop and maintain such integration. Integration with shopping carts is likely the greatest challenge in developing different kinds of eCommerce applications. Connecting multiple systems for data exchange is brain-racking, costly, and requires tons of technical work.

Fine work will take a very long time, particularly if you wish to connect to multiple platforms. And now consider the costs. Not only those you will encounter in the production of integration but also those linked to the continued maintenance of fully prepared and ongoing integration.
