In every day life, application programming interfaces (APIs) are fundamental for allowing different softwares or applications to communicate with each other.

What is an API?

An application programming interfaces or API is a platform that allows different pieces of software to communicate with one another. We use lots of them in everyday life: using ride-sharing apps, like Uber, or applications like Instagram that relies on Apple's APIS to use our device’s camera or microphone.

APIs can be found in various domains. Many web, mobile apps or even devices (google home, Amazon Echo, etc.), rely on web APIs.

A web API basically use the same technologies as web browsers to allow different services to communicate with one another.

Web APIs can allow applications :

  • to retrieve data
  • perform new actions beyond their built-in capabilities

The API gives a response, the application then analyses it and displays it. Depending on the functionality provided by the API, there may be an additional layer of security involved, such as sending a unique key.

Let's consider your experience using-ride a sharing mobile app like Uber. When using this type of service, the application makes a request to the API checking the availability of a car near your current location. The API access to the drivers' data and returns it as its response.
