20 APIs (Application Programming Interface) to Boost Your Business

20 APIs (Application Programming Interface) to Boost Your Business
In this article, we will explore: what an API (Application Programming Interface) is, how it works, and its benefits. Finally, we'll list 20 APIs that could help you save time, money, and productivity. In today's dynamic and competitive world, it is often necessary to interact with external applications to stay on the cutting edge. Indeed, the effective management of a company may require the use of CRM systems, ERP, marketing tools. You can also request partnership management solutions. Fortunately, big players, such as Google, Facebook or HubSpot, offer integrated solutions to meet these evolving needs. This is where APIs (Application Programming Interfaces) come in. They play a crucial role in enabling connection with the offers of these companies.

What is an Application Programming interface?

An API, or Application Programming Interface, is a set of rules and protocols that allows different software applications to communicate with each other. It's mostly a way for programs to interact and share information, features, or resources with each other. Imagine the API as an intermediary that:
  1. Take a request from an application,
  2. Passes to another (or to a component of the operating system),
  3. get a response and then forward it to the application that made the original request.
For example, if you're using a weather app on your phone, that app probably uses an API to pull weather data from an online service. APIs can be public (or open), which means they are available for use by other developers, or private. In other words, when an API is private, it is used inside the company that developed it. They are essential tools for modern software development. Indeed, they make it possible to create more complex and integrated applications. Plus, you can take advantage of features developed by others without having to start from scratch.

How do APIs work?

An Application Programming interface works by exposing a specific set of methods, classes, functions, or procedures that other software can use. In other words, they define the type of interaction that can take place between different software. Here's how an API usually works:

1 - Request;

An application sends a request to an API. This request usually includes the information the application needs, as well as instructions on how that information should be handled.

2 - Treatment;

The API receives the request and interprets it. Then, it performs the required actions to obtain the requested information. This may involve:
  • retrieve data from a database,
  • to perform calculations,
  • or any other action required to respond to the request.


After the API processes the request, it returns a response to the application. This response usually contains the requested information, but it can also contain information about the status of the request (for example, whether it was successful or not).

A small example;

To give an example, consider a flight reservation application. When a user searches for a flight, the app sends a query to the airline's API, with details like flight date, destination, etc. The Application Programming Interface processes the request, searches for available flights in the airline's database, and then returns this information to the application. Finally, the application displays the flights available to the user. It is through this interaction between applications via APIs that we can have a smooth and integrated user experience, even when several different services are involved.

The benefits of APIs

APIs have become an essential component of web development and software technologies for multiple reasons. They offer a multitude of qualities, including:

1. Improved productivity

With an Application Programming interface, developers don't have to build everything from scratch. They can take advantage of features from other apps and services, which can save time and allow them to focus on the more important aspects of developing their own app.

2. Cost reduction

Because APIs allow reusing existing functionality rather than redeveloping it, they can significantly reduce development costs. This is especially useful for startups and small businesses that have limited resources.

3. Acceleration of the development process

Through APIs, developers can speed up the development process of their applications. They don't need to understand all the details of the application or service they are interacting with, they require understanding how to use the API.

4. Easy integration

APIs facilitate the integration of different applications and services. This means that users can have a smoother and more integrated experience, even if they use several different services. For example, a travel booking application might use APIs to integrate services from multiple airlines, hotels, and car rental companies.

5. Innovation

By exposing functionality and data through APIs, companies can enable other developers to create new applications and services that leverage that functionality and data. This can lead to the emergence of new ones. In summary, APIs are essential to modern web development because they enable increased interoperability, facilitate the integration of various services, speed up development, reduce costs and promote innovation.
