The OpenAPI Specification (OAS) defines a standard, programming language-agnostic interface description for HTTP APIs, which allows both humans and computers to discover and understand the capabilities of a service without requiring access to source code, additional documentation, or inspection of network traffic. When properly defined via OpenAPI, a consumer can understand and interact with the remote service with a minimal amount of implementation logic. Similar to what interface descriptions have done for lower-level programming, the OpenAPI Specification removes guesswork in calling a service. The OpenAPI Specification has a solution – reusable components that can be used across multiple endpoints in the same API. These components are defined in the global components section and then are referenced in individual endpoints. The Specification defines various types of reusable components: Schemas (data models) Parameters Request bodies Responses Response headers Examples Links Callbac...
