A REST API (also known as RESTful API) is an application programming interface (API or web API) that conforms to the constraints of REST architectural style and allows for interaction with RESTful web services.
REST stands for representational state transfer. It is an architectural style that defines a set of rules in order to create Web Services. In a client-server communication, REST suggests to create an object of the data requested by the client and send the values of the object in response to the user.
As you know well, API stands for Application Programming Interface.
API Gateway REST APIs use a request/response model where a client sends a request to a service and the service responds back synchronously. This kind of model is suitable for many different kinds of applications that depend on synchronous communication.
The REST framework was introduced by computer scientist Roy Fielding in 2000, and today it shapes how we view, modify, and transfer content online. Many of the most popular web and cloud companies use REST APIs for their applications, including Facebook, YouTube, Twitter, and Google.
You can find REST APIs all over the web — you’ve likely used some today without realizing it.
The Facebook Basic Display API offers access to profile information, photos, and videos. You can utilize this API and others to build apps that pull this user information and integrate it into your own product. Facebook also has a Graph API available for professional Facebook accounts to manage their online activities.
Whenever you are using your social media accounts like Facebook or Google over a third-party application, you are bringing APIs into play. For example, login or data sharing purposes, where API enables you to access.
