Using APIs

Question 1

Purpose of APIs

Answer 1

APIs enable applications to communicate and share data or functionality, enhancing modularity and integration between services.

Example - A travel app using an API to pull real-time flight data from an airline’s system to display to users.

Question 2

Advantages of APIs

Answer 2

APIs streamline integration, allow for reusability, enhance scalability, and speed up development by leveraging external data or services.

Example - Using a payment API, like Stripe, lets an app handle transactions without building its own payment system.

Question 3

APIs - Examples of Use

Answer 3

APIs are used for integrating third-party services, automating tasks, and accessing data across different systems.

Example - A weather app using an API to fetch live weather data or a social media app using APIs to share posts across platforms like Twitter and Facebook.

Question 4

How APIs Work

Answer 4

APIs enable communication by sending requests (e.g., GET, POST) from a client to a server, which processes the request and sends back a response.

Example - A mobile app sends a GET request to a weather API, and the server responds with the current temperature data.
