It is used in almost all programs, from mobile applications to complex flight control tools. It makes a massive difference for eCommerce sites, and today we want to discuss why.

How is the API used these days?

All the apps and websites you are currently using actively use the API. Every industry has found different benefits to using the technology. For example, banking uses this technology to pay for goods in retail stores using a smartphone, transfer money from one bank to another online, and much more.

It is also widely used in various social networks. So, Facebook uses this to perform site searches by name, location, or included images tagged with a particular person.

In turn, eCommerce sites widely use this technology to expand their customer base. So, for example, using the API, you can attract new customers through social networks or sell the same products on different sites.

The value of the API for developing a successful business is now challenging to overestimate. However, you can achieve good results using this technology to the fullest. TestFort can test any API to ensure it works well and makes your business more efficient.

Benefits of using the eCommerce API

There are several essential benefits of using the API for eCommerce sites; today, we will discuss the most important ones.

Quickly scale to meet changing needs

Practice shows that most customers place orders through their smartphones, which is as fast and convenient as possible. Today, no one wants to call an online store to find out if the right size is in stock. As a result, you need to make it easier for customers to access inventory.

This decision also means you reduce the burden on your employees, which means they will make fewer mistakes and get on with more important things.

Fast scaling

For your company to remain competitive, you must keep an eye on customer needs, which are constantly changing, and make adjustments accordingly. So, you must remove some unnecessary features and add those urgently needed.

So, for example, if your product goes viral on social media, you don’t have time to develop all the software testing steps. Internal APIs connected to cloud providers keep sites up and running when traffic spikes would typically bring them down. In this case, this technology could mean more sales.

Good data security

eCommerce sites strive to make storing personal data and transactions as secure as possible. Not only financial security depends on this, but also on the reputation of the resource.

APIs allow you to provide reasonable security of stored information from intruders, who can then use it against clients. In addition, it makes transactions faster and more secure.

Examples of APIs eCommerce sites regularly used

Practice shows that eCommerce sites use various APIs at almost every stage of their work, from interacting with a client to delivering a product to its destination. It is worth saying that this technology is constantly evolving, which gives you new opportunities to modernize and automate your business.

Product information to display features

Thanks to this technology, users can get the most up-to-date information from a common database about the cost of goods, their availability on the site, and even track delivery. It allows you to maximize the quality of service and speed up the process of deciding to purchase a product.

Search APIs for better navigation

Creating a large online store is a rather difficult task that requires a lot of time, knowledge, and money from you. Creating convenient navigation with many products becomes a challenging task. In this case, search APIs are used. They allow you to find the right product and offer users a similar position.

Payment APIs

Payment for goods in the online store should be made as quickly and efficiently as possible; otherwise, the client may refuse to purchase the necessary goods. In this case, payment APIs come to the rescue. Not only do they make the payment process as easy as possible, but they also make it as secure as possible. To ensure this, it makes sense to conduct different types of stress testing. They must check how the system behaves in extreme situations.


To remain competitive, an online store must use the API. It will simplify navigation on the site as much as possible, provide the necessary information to potential buyers and increase the level of security. For this to work correctly, it is essential to conduct a complete test. It will allow you to identify the slightest errors, creating a high-quality eCommerce site.
