A platform API is a set of programming tools, protocols, and routines provided by a software platform that allows external developers to build applications and services that interact directly with that platform. It provides access to the platform's core features, data, or services, enabling third-party apps to extend the platform's ecosystem. Platform APIs are designed to support a broader range of third-party apps and a scalable ecosystem around the platform.
