What Is An API?

Before we dive into the understanding of eCommerce API, it is better to first learn what an API is. An API is the acronym for Application Program Interface and is defined as the set of protocols, routines, and tools that are essential for building software applications. An API basically specifies how the components of the software should interact.

Besides these, APIs are also utilized for programming various GUI or Graphical User Interface components. In simple words, we can say an API helps you declare an interface to let you interact with its logic or program. The interaction takes place in such a way that you don’t know what is actually happening in terms of the logic or program.

It puts a mask on the whole complexity of the system thus leaving an easy-to-use and consume system at the front.

What eCommerce APIs Are All About

By definition, eCommerce APIs are tools that help developers transfer information from one software to another and then use this data in a single user interface. To enumerate, API stands for Application Programming Interface. In the context of APIs, the word Application refers to any software with a distinct function. The interface can be thought of as a service contract.

Perse, a contract of service between two applications. This contract defines how the two communicate with each other using requests and responses. These APIs work as an extensible platform that integrates with various solutions. So that companies can take advantage of their existing functionality without building features from scratch.

In simple terms, eCommerce APIs are a set of commerce functionalities that are exposed to your eCommerce platform through APIs. These functionalities may include payments, carts, checkouts, orders, and more. It’s a software tool that an online eCommerce store can program in order to simplify and automate plenty of fulfillment procedures.
