In the current world of eCommerce competition, there can be no compromise on innovation. Being an eCommerce software provider, you are aware of the importance of providing tools that will help merchants to optimize their processes, improve customer experience and, as a result, increase sales. This is where Digital Commerce APIs come into play.

These APIs operate as bridges to make your software to seamlessly interact with most eCommerce platforms. Consider your inventory management software being able to sync with listings on various platforms or your marketing automation tool being able to pull sales data from multiple stores in real-time. This is the transformative potential of Digital Commerce APIs.

This guide will provide you with all the information and tools necessary to successfully implement Digital Commerce APIs into your applications. 

What is a Digital Commerce API?

A Digital Commerce API is defined as a group of interfaces that enable an eCommerce platform to communicate with other software. These APIs enable eCommerce platforms to communicate and share information with other systems and services, including payment processors, inventory, CRM, and marketing automation. Digital Commerce APIs are interfaces that allow for the exchange of information between different software, thus allowing businesses to expand the capabilities of their eCommerce operations without having to write complex software code. This can entail everything from automatically updating a store with new products to synchronizing the stock across various sales platforms, order fulfillment, and customer information in real-time.

How Does a Digital Commerce API Work?

A Digital Commerce API works by defining a set of rules and standards that enable the various software applications to communicate and interact with each other. For eCommerce software providers and developers, this means that they will be able to add various functionalities into their software without having to start from the basics or having to learn how the other system works.

For instance, a Digital Commerce API could provide interfaces that enable a developer to access product data, modify stock, make transactions, or trigger delivery—all using HTTP methods such as GET, POST, PUT, DELETE, etc. These APIs are usually RESTful, making them versatile and functional in various applications and devices.

In detail, when a Digital Commerce API gets a request, it performs this request against the business rule and data in the backend systems of the API. It then responds with the requested data in a format that is easy to handle and display, such as JSON or XML, depending on the need of the requesting application. This flow of information also allows for real-time data updates and interaction, which is a very important characteristic when it comes to the dynamism of today’s modern eCommerce.

Examples of Commerce APIs 

The world of eCommerce is built on connections, and Commerce APIs serve as unseen links between different systems. Here is an example of one.

Shopping Cart APIs enable the software to communicate with a shopping cart and its features. Think of a loyalty program software that connects with the shopping cart API to instantly assign points or offer discounts. Also, these APIs can be used by inventory management software to reflect the stock in real-time depending on the purchases.

The Possible Way to Develop Integration with Commerce APIs

The process of integration with commerce APIs can appear challenging because of the amount of APIs available and their nature. Every platform has rules and data structures that are different from those in other platforms.
API2Cart is a perfect example of the service which enables developers to integrate their applications with more than 40 shopping carts simultaneously. This greatly helps to minimize the amount of work and time necessary for integration development, as it ‘hides’ all the specifics of various commerce APIs behind a uniform structure that is less troublesome to deal with and update.

In summary, it can be said that the discussed digital commerce APIs are indispensable for those companies that strive to improve their online presence and optimize their processes. With the help of these APIs, it is possible to integrate solutions with other third-party services and automate many functions.
