API (Application Programming Interface) documentation

API documentation is a set of instructions and details that explain how different software systems can communicate with each other through an API (Application Programming Interface). It describes the available functions, input parameters, output results, and how to properly use the API. This helps developers integrate or connect different applications efficiently, ensuring they understand how to send and receive data correctly. In essence, it's a user guide for software to interact smoothly, making it easier to build, extend, or connect digital services or features.
