Which type of integration performs tasks without an end-user context?

• A. Public App
• B. Web App
• C. Server-to-Server integration
• D. Mobile App

Answer: (C)

Integrations that run in the back-end without a user present operate without end-user context. Server-to-server integration is exactly that: one system communicates directly with another using APIs, messages, or events, often automated and triggered by backend processes. There’s no user interface, no user session, and no human-driven flow involved, just machine-to-machine communication with authentication via service credentials.

By contrast, public apps, web apps, and mobile apps are built for people to interact with. They provide user interfaces, collect input, present data, and guide user actions, all of which center on an end-user experience. Because they rely on human interaction, they inherently carry end-user context. Therefore, the type that performs tasks without end-user context is server-to-server integration.
