Yes, I'm familiar with APIs. An API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate and exchange data or functionality. For example, in a banking or fintech project like those at Cyber Village, we might integrate with third-party payment gateway APIs to process transactions securely without building the entire payment system from scratch. As a BA, I work with stakeholders to define API requirements, document endpoints, data flows, and ensure they meet business needs.
