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.
