API Integration Tools

Updated 9 July 2024 |

As an eCommerce software vendor, it is important for you to integrate your software with shopping platforms and marketplaces. They provide you with the data you need for your software to perform its core functionality. To establish a seamless connection with all the required platforms, you can use API integration tools. They can save you from the challenges associated with integrations.

What is an API?

To start with, an API (Application Programming Interface) is a piece of software code that acts as an intermediary between two applications. It is a medium of communication that allows those applications to interact with each other and transfer data. It forms a very important part of API integration software because they allow to connect with the shopping platforms’ API and retrieve data from the platforms.

APIs use abstraction—that works in the back-end of applications—to hide the internal complexities of integration. Therefore, you can relax with your software as it fetches data from eCommerce platforms with the help of APIs.

The ability to interact with other systems and extract data from them to use for its purpose makes an eCommerce software solution full-fledged for the retailers. At the same time, it saves you enough time, money, and resources that you would otherwise invest in different ways to get stores’ data for your software. Moreover, with API integration tools, you can speed up the process.

API Integration Examples

Before you get to know more about API integration tools, let’s first understand the basic concept behind API integration. It is definitely a constant part of your everyday operations without you even realizing it.

  • Google Flights (or any other flight booking system) - These systems are connected with airline databases via APIs. These databases contain information about various flights, including costs, timings, places, etc. Google Flights integrates with these databases, fetches information from them in one place, and helps users find all the details easily.
  • Siri/Google Assistant - These are virtual assistants that use APIs to connect you with your default applications on the phone when you look for something via Siri or Google Assistant. For instance, if you are looking for directions or some general information via Siri, it will plug you into your default app for navigations (Google Maps in case of Google Assistant) or search engine, respectively.

What are API Integration Tools?

API integration tools are the services that facilitate communication between multiple APIs of different applications. They make it easy for developers and software vendors to establish connections between various apps of their choice.

With API integration software, you can connect your software with multiple applications without having to bear the costs, delays, and resource consumption of in-house integration development. Moreover, these tools allow businesses to incorporate data better without compromising its quality or efficiency.

An API integration tool uses agile methodology to reduce the development time and the overall costs associated with integrations. Even if you build APIs or use them for your organization’s requirements, API integration tools will help you manage your functions better.

CartRover is a one-stop solution for vendors who develop software for logistics and fulfillment providers. It can help them sell automated SaaS solutions and allow the end clients to streamline their business functions.
