API governance is a critical component of successful digital transformation, requiring the establishment of strong schema foundations, leveraging OpenAPI for standardized APIs, balancing centralized and federated models, implementing automated linting for quality assurance, and aligning API governance with business goals. Effective API governance begins with schema, particularly JSON schema, and requires a holistic understanding of diverse perspectives. The Open API Specification (OAS) provides a standardized way to describe APIs, enabling automated tooling, documentation, SDKs, and policy enforcement. Implementing rules through tools like Spectral, Vacuum, and APIMatic is essential for linting APIs and schemas. API governance extends beyond technical considerations, encompassing business aspects, and should align with business goals to drive organizational objectives.
