    Application Programming Interfaces (APIs) allow services to communicate with each other • Software has become more complex and collaborative over the years. Developers no longer need to create every service from scratch. • APIs allow developers to access data from a service (like Google or Twitter) without any knowledge of how the codebase has been implemented.
