Policies
Parameter Types
Getting parameter types right -- integers, strings, arrays, numbers -- with proper formats and constraints prevents a whole category of integration bugs before they happen.
Schema Property Type
Property types define what kind of data each field holds. Getting the types, formats, and array item definitions right is fundamental to an API that works predictably.
Schema Constraints
Schema constraints like min, max, minLength, maxLength, and enum values are the guardrails on your data. Without them, anything can flow through your API and garbage in means garbage out.
