What is an API?

An API (Application Programming Interface) is an Application Programming Interface . What does it mean? It means that it is a resource that is used to integrate systems in a secure way, facilitating the exchange of data while monetizing its access.

Therefore, the API can be defined as a set of patterns and programming routes that grant access to software from the web. Currently these APIs are developed by software companies for other programmers to create services and products that are related to the application. That is why it is not surprising that many companies offer users the codes and manuals of the applications, so that they can find ways to integrate with other sites and applications.

As you will see, then, the API allows you to interconnect two or more applications without requiring user intervention thanks to the use of codes and protocols that help define specific behaviors, perform actions or use tools. It should be noted that, to further facilitate integration, the API is not visible in the user program interface so that it cannot be seen when an application or web is being used.

In recent years, the use of APIs has spread rapidly, which is why they have also come to be integrated with plugins, that is, the add-ons and software functionalities with the aim of exploiting as much as possible the real capabilities of the software. plugin.
