What is An API and How Do They Help?

API integration enables systems to exchange data sources by connecting two or more applications through APIs. API integration allows processes at many different organization levels to keep data in sync, increase productivity and generate revenue.

With the help of APIs, different systems communicate with each other, resulting in an interconnected network that seamlessly shares data. This process not only helps to create a natural split between your front-end and back-end operations but also shares the data between multiple systems that help your business work at a high level.

APIs increase growth, innovation, efficiency, agility, and productivity ― all of which have a beneficial effect on profitability. Indeed, it would not be much of a stretch to say that under the hood, APIs are the engine powering the digital economy, which is now evolving quickly in the eCommerce industry.

For example, if you need to call the news aggregator API and request ten of today’s most popular news from it, you can use the “top news” command, and the service will respond by sending you the most recent collection of updates.
