What is API?

1. What is API and how does it work?

API derives from the English expression Application Programming Interface, which can be translated into Portuguese as application programming interface. The API, or application programming interface, is a set of standards that enables cross-platform communication through a set of parameters and protocols.

Developers can use APIs to create new programs and applications that can communicate with other platforms.

2. What is the function of an API?

A basic function of an API is to facilitate and simplify the work of developers, as well as to provide a framework for the creation of new platforms. With the use of APIs, it is no longer necessary to write custom code for each function to be performed by a program, which simplifies the development of new applications, software and platforms in general.

3. What are the most common types of APIs?

Public APIs

They are made available to the public along with their documentation and dispense with complex processes to validate the identification of their clients, such as registration.

This allows more people to learn about the developer's brand and product, which makes it easier to strengthen the relationship with the company's target market.

At the same time, a public API requires more control and attention over the use of the interface by others. This ensures that the security and standard that was originally offered is maintained.

Partner APIs

With a partner API, your company has more control over who can and cannot use that interface. Typically, an access program is developed only for your business partners.

Private APIs

Private APIs offer greater restrictions on access and available data and can be lucrative for customers. 

They can also be used to optimize internal processes. In this case, only internally authorized personnel can access the information.

4. What are the main advantages of an API?

You ca have greater control over your company's access permissions by using an API. It allows you to identify users who have attempted to access your system, as well as the location from which the request originated. In addition, you can choose what information is made available to the customer at the time of integration.

It also enables faster integration of systems that are incompatible, without the need to assign a development team to the task. In addition to faster information exchange, this reduces the time, financial resources and data used in the environment.
