The REST API frameworks are used wherever there is a need to provide data from the server to the user.
Since the REST architecture separates the client and server, it is easy to extend, allowing the application to scale without much effort.
This architecture is very flexible and allows developers to handle different types of queries and data formats.
The technology allows receiving and modifying the data and states of remote applications by transmitting HTTP calls over the Internet or any other network.
REST architecture is designed to create a well-structured approach to writing application and website frontends.

Representational State Transfer, or REST API service, refers to a type of software architecture that imposes conditions on how an API should work. When a client requests a resource using a REST API, the server transfers back the current state of the resource in a standardized representation.
REST web service itself is a part of the integration framework. The goal of the REST API in the framework is to handle requests from external consumers. The framework is the skeleton holding the library or libraries. The API is the programming interface allowing you to interact with another application or operating system.
REST API web service is helpful only when the data from one of the requests is successfully delivered. With the help of the REST API, you can migrate from one server to another, as well as update the database at any moment. REST basically is a style of web architecture that governs the behavior of clients and servers. While API is a more general set of protocols and is deployed over the software to help it interact with some other software. REST is only geared towards web applications. And mostly deals with HTTP requests and responses.
