API Strategy
API Strategy for SAP landscapes covers how architects decide which integration technologies, governance models, and lifecycle practices to use when exposing and consuming APIs across ECC, S/4HANA (on-premise, private cloud, public cloud) and BTP. It addresses clean core alignment, security, versioning, and long-term maintainability of the integration landscape.

Lessons in this topic
- API Types, Patterns and Governance Foundations in SAPCovers the main categories of SAP APIs, common integration patterns, and the governance foundations needed to manage them consistently across a landscape.
- Why API Strategy Matters in SAP LandscapesIntroduces the business and technical reasons SAP architects need a deliberate API strategy, and how it differs from ad-hoc point-to-point integration.
- Choosing Integration Patterns: Point-to-Point, API-Led Connectivity and Event-Driven DesignCompares point-to-point, API-led (managed API layer) and event-driven integration patterns and gives criteria for choosing between them in an SAP-centric landscape.
- Securing APIs Across a Hybrid SAP Landscape: Authentication, Authorization and Principal PropagationExplains the security decisions an architect must make when exposing SAP APIs across ECC, S/4HANA and BTP, including authentication mechanisms, authorization scoping and principal propagation trade-offs.
- Long-Term API Governance, Cost Control and Roadmap EvolutionHow to sustain an API strategy over multi-year S/4HANA and BTP evolution: governance operating model, cost accountability, deprecation policy, and roadmap sequencing to avoid API sprawl and technical debt.
