RESTful API vs. HTTP API: A Concise Explanation

RESTful API is a web service architecture built upon the HTTP protocol. It utilizes HTTP verbs (GET, POST, PUT, DELETE, etc.) to manipulate resources and leverages HTTP status codes and headers to describe the resource's state and related information.

HTTP API refers to any interface that communicates using the HTTP protocol, encompassing both HTTP requests and responses. An HTTP request comprises the request line, request headers, and request body. Conversely, an HTTP response includes the status line, response headers, and response body. HTTP APIs are employed to facilitate communication between diverse applications, such as web services, mobile applications, and more.
