SAP / SAP Senior Level (10+ yrs) Interview questions
How do you approach API management and governance for extensions built on BTP?
As the number of extensions and integrations grows across an enterprise, uncontrolled API sprawl becomes a genuine risk — duplicated APIs doing similar things, inconsistent versioning practices, and unclear ownership. A deliberate API governance approach addresses this before it becomes unmanageable.

B --> D[Access control and rate limiting via API Management]
B --> E[Clear ownership per API]
Practically, this means establishing consistent API design standards (naming conventions, versioning strategy, error response formats) enforced across teams, maintaining a central catalog so developers can discover and reuse existing APIs rather than building duplicates, and using BTP's API Management capabilities to enforce access control, rate limiting, and monitoring consistently — treating APIs as a managed, governed product rather than an incidental byproduct of each individual extension project.
