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.

URI

POST /v1/{project_id}/apic/instances/{instance_id}/apis

Only one parameter of each API can be bound with unique orchestration rules. The number of orchestration rules that can be bound is limited by quota. For details, see "Quotas" in ROMA Connect Service Overview.
