Creating an API

Function

This API is used to create an API. An API is an interface that encapsulates a set of service capabilities. The definition of an API is divided into two parts: how the API is called by users, and how ROMA Connect accesses the actual backend service requested by users. Three backend types are supported: HTTP/HTTPS web, FunctionGraph, and Mock.
