API for Beginners
This document introduces APIs and how they are used by developers. It explains that APIs allow programs to interact with other applications and services to access useful data and functionality. Developers can use APIs by making HTTP requests to consume data and build their own applications. The document provides examples of popular APIs like Google Maps, Twilio, and Meetup that developers integrate into their applications. It also discusses the differences between making API calls and using webhooks to receive automatic notifications from a service.
