API core concept Correct Ans-- API is designed first using an API specification for rapid
feedback. The APIs that have the most value and use for the enterprise are more like products
than code. They are designed to be consumed by specific audiences (e.g., mobile developers),
they are well-documented, and they are versioned so users can have certain expectations of the
API maintenance and lifecycle. API development best practices enable the full API lifecycle from
design, build, test, through to deployment. APIs developed with software development lifecycle
methodologies in mind connect to any application or source of data and possess a powerful set
of capabilities to process and compose the data. These APIs are secured by design through
automatic API registration and policy management, and plug into a fully-featured platform for
analytics, portals and developer communities. Most importantly, APIs developed with these
best practices are easy to build, productize, deploy and change. Change is a constant; therefore,
the API should be a core strategic element in fast deployments, rapid changes, innovativeness,
and experimentation.
