API stands for Application Programming Interface which allows apps to interact with each other by enabling them to request and share data.
APIs work in the background, facilitating communication between different apps to perform various functions like retrieving data or making transactions.
APIs commonly use JSON format to exchange data, which is then processed by the app to present the information to the user in a readable format.
Using APIs, developers can integrate functionalities like live weather updates into their apps, making it essential for app development and enhancing user experience.
