Which APIs are primarily concerned with user experience?

Experience APIs are specifically designed to cater to the needs and preferences of the end users, focusing on how users interact with the system and what their specific requirements are. Unlike other types of APIs that handle backend logic or data integration, Experience APIs are tailored to provide a direct interface for user-facing applications. They often aggregate multiple data sources and deliver the information in a manner that enhances usability, ensuring that the experience is seamless and engaging for the user.

For example, when developing a mobile app or a web portal, the Experience API may format and optimize data in such a way that it aligns perfectly with the user interface and the user journey, making interaction smooth and intuitive. This contrasts with other types of APIs, such as Process APIs, which focus on processes and business logic; System APIs, which interact directly with underlying systems and data sources; and Integration APIs, which are primarily concerned with the integration and communication between various systems and services. Each of these plays vital roles in a larger architecture, but they do not prioritize user experience in the same way that Experience APIs do.
