What Is API

 

Application Programming Interface 

The acronym "Application Programming Interface" (API) refers to a kind of software interface that enables two apps to communicate with one another independently of any input from the user. An application programming interface (API) is a compiled set of software processes and functions.

In its most basic form, application programming interface (API) refers to any piece of software code that may be read or run. An application programming interface, or API, is a kind of code that enables many pieces of software to connect with one another and share data.

Types of APIs

Open APIs

Alternately referred to as Public APIs. These application programming interfaces are open to the public and do not have any access limitations.

Partner APIs

Because many APIs are not open to the general public, you will need to acquire certain permissions or licenses in order to use them.

Internal APIs

Internal or private. These application programming interfaces (APIs) are built by businesses for use in the systems they operate internally. You may increase the productivity of your staff with the aid of this.

Composite APIs

This category of APIs brings together a variety of data and service APIs.

Web Services APIs

SOAP: It specifies messages in XML format, which is the language that web applications use to interact with one another.

REST: It may GET, POST, PUT, or DELETE data by using the HTTP protocol. Its primary purpose is to optimize the use of previously collected data.

JSON-RPC: It defines a few different data structure kinds and utilizes JSON as its data transmission format. Additionally, it is a lightweight remort procedural call.

XML-RPC: It is based on XML and uses HTTP for data transfer. This application programming interface (API) is used extensively in the process of information sharing between two or more networks.
