This is a technical talk on public API design. The audience will learn about the overall governance process with a focus on design, compliance with standards, relying on patterns and OpenAPI specification, and significance of accurate terminology and non-ambiguous use of nouns and verbs. Following consumer-centric approach, providing predictable and understandable names across capabilities, and trying not to reinvent the wheel on every new API is common to any API program. API standards and design process are true elements of success.
