An API (Application Programming Interface) is a programming interface that allows different software and systems to communicate with each other. It enables automated data exchange and function calls. Businesses need APIs to connect various applications – for example, an e-shop with an accounting system, CRM with marketing tools, or logistics services. This helps save time, reduce errors, and streamline operations by automating routine tasks. "Cezar's" programming services include custom API development tailored to specific client needs.
