1. SEMINAR ON APIs An Introduction to Application Programming Interfaces By. Khan Amer Shabbir Under Guidance. Prof. Deokate V.P

2. Introduction APIs, or Application Programming Interfaces, are essential components of modern software development. They enable the interaction and data exchange between various software systems, making them an importan t part of our digital world.

3. What is an API? An API, or Application Programming Interface, is a set of rules and protocols or lines of code An API is like a bridge that allows two different software systems to communicate and interact It defines how requests and responses should be structured and what data can be exchanged.

4. How APIs Work APIs work by providing a way the method (GET, POST, etc.) and any required parameters. This can be done through HTTP requests, function calls, or other communication methods, depending on the API type. The API server processes the request and performs the necessary actions The response is sent back to the client in the specified data format (e.g., JSON or XML ). The client receives the response , and takes action based on the information got from the API.

5. Common API Types Web APIs: These are widely used for web and mobile applications and follow protocols like REST and SOAP . App Number Of Vehicle Search (API hit) Information got

6. Common API Types Library APIs: These provide predefined functions and command for specific programming languages . provide a set of functions, or classes that allow developers to access and use specific functionalities or resources within a particular programming language or framework . 1 Python: NumPy , Pandas, Django /Flask 2 Java Standard Libraries: java.awt and javax.swing , JUnit 3 JavaScript: React, Vue.js, Moment.js

7. Common API Types Hardware APIs: These enable software to interact with hardware components like printers, cameras, and sensors . Operating System APIs: These allow applications to interact with the operating system.

8. API Authentication & Security Security is a critical aspect of APIs. Protecting data and preventing unauthorized access are essential. API authentication is the process of verifying the identity of a client (an application or user) that is trying to access an API It ensures that only authorized and authenticated entities can make requests and access the resources provided by the API . It prevents unauthorized access And its protects sensitive data and resources. Common Methods of API Authentication API keys, OAuth , and token-based authentication .

9. Benefits of APIs APIs offer numerous advantages, including increased functionality, faster development, and the ability to integrate with third-party services, leading to enhanced user experiences.

10. Conclusion APIs have revolutionized the way software interacts and are at the heart of modern application development. Understanding how to use and design APIs is key to building powerful, interconnected applications . Reference Chat.openai.com Google.com Wikipedia.org Javatpoint.com Stackoverflow.com
