An API, or Application Programming Interface, is a set of rules. It allows different software applications to communicate. APIs define the methods and data formats for this interaction. Websites use APIs to connect with other services. For example, a weather website uses an API to fetch weather data. It sends a request to the weather service. The service responds with the data in a predefined format, like JSON. The website then displays this data to users. Another common use is social media integration. Websites can allow users to log in using their social media accounts. They do this through APIs from platforms like Facebook or Twitter. The API handles authentication and user data retrieval. APIs also enable e-commerce functionalities. Online stores can use payment gateway APIs. This allows them to process payments securely.
