Creating an API

Function

This API is used to create an API. API is an interface that encapsulates a set of service capabilities.

The definition of an API defines how the API is called by users and how ROMA Connect accesses the actual backend service requested by users. APIC supports three backend types: HTTP/HTTPS web, FunctionGraph, and Mock.

URI
