Last updated 14 September 2026

What is API Calls?

APIs, short for Application Programming Interfaces, are software-to-software interfaces. Meaning, they allow different applications to talk to each other and exchange information or functionality. This allows businesses to access another business’s data, piece of code, software, or services in order to extend the functionality of their own products — all while saving time and money. There are several options available to make API calls from your React.js applications.
