APIs sit at the center of modern digital products. Every mobile interaction, dashboard update, and system integration depends on a reliable backend layer that moves data between systems with precision and consistency. As products grow more connected and more distributed, the quality of the API often determines how quickly a business can adapt.
This shift toward API driven architectures has changed how teams build software. Backend systems are no longer tied to a single interface. They are expected to support web applications, mobile clients, internal tools, and external partners, often all at once.
Ruby on Rails supports this model directly through its API focused capabilities within the broader rails framework.
