Schema types are the foundation of the digital objects being passed back and forth via the web for use in desktop, web, mobile, device, and artificial intelligence applications. Schema types single the structure of API requests and responses, allowing for more clarity and specificity about what is expected in exchanges with APIs.
OpenAPI schema types are defined by another open source specification called JSON Schema, which provides the ability articulate the structure and form of digital objects use within APIs. Schema types are what makes API traffic known, observability, and something you can validate, so make sure have types defined for all of the schema used as part of API operations.
