Some of you may ask, what is an API? How does an API work? What makes APIs so popular among programmers? API is an acronym for Application Programming Interface. API is a web service, which is a standard used to apply data exchange on the internet network written in different program languages or running on different platforms.
APIs are composed of layers and various elements such as functions, protocols, and tools that allow developers to create applications. The purpose of using APIs is to speed up the development process by providing separate functions so that developers do not have to repeatedly create similar features. The use of APIs will be felt when the desired features are complex. There are many different types of API systems that developers can use, including operating systems, libraries, and the web.
APIs allow developers to integrate two parts of an application or with different applications simultaneously. Implementations of APIs include the well-known ones are SOAP and REST.
SOAP (Simple Object Access Protocol) is a protocol for exchanging structured information in the implementation of web services on computer networks. SOAP uses the extension XML (Extensible Markup Language) as its message format, and relies on other application layer protocols, especially HTTP and SMTP.
REST (REpresentational State Transfer) is a software architecture for web-based distributed systems. By Roy Fielding the term representational state transfer was introduced in 2000 in his doctoral dissertation. He is one of the main authors of HTTP specification versions 1.0 and 1.1.
