What is an API (Application Programming Interface)?

An API (Application Programming Interface) is a set of rules and protocols that allows different applications to communicate with each other. In other words, it is an "interface" between two software systems that allows one to send and receive data or functionalities from the other.

Example:
Imagine you're using a weather app on your phone. This app sends a request to the API of a weather forecast website, receives a response (e.g., the temperature), and shows it to you.

Main Types of API:

• REST API - Uses HTTP protocols (GET, POST, PUT, DELETE) and often returns data in JSON format.
• SOAP API - An older format that uses XML to transmit data.
• GraphQL - Allows specific queries for exactly defined data.

What is a Web Service?

A web service is a type of API that is accessible via the internet and uses web technologies (typically HTTP) for communication between different devices or systems. Web services are designed to allow data exchange between remote systems.

Key Characteristics of Web Services:

• Accessible over the network - You can use them from anywhere on the internet.
• Language independence - Systems interacting through a web service can be written in different programming languages.
• Standardization - They use standards like XML, JSON, HTTP, WSDL, and others.

Difference Between API and Web Services

API is a more general term that can be used for communication between various components of software applications, including local ones (on the same machine).
Web services are a specific type of API that operates over the internet and uses network protocols.

Example of Interaction:

• API: A video editing application uses the API of a graphics processor to perform complex calculations.
• Web Service: An e-commerce website uses a web service for payment processing to handle customer payments.
