OpenAPI

The OpenAPI integration calls any service that publishes an OpenAPI specification, without anyone building a node for that service first.

What it gives you

Node	What it does
OpenAPI action	Calls one operation from a specification you point it at, with a form built from that operation's own parameters.

What it needs

No connection of its own. Each step names the specification it calls, so one automation can reach several services and two steps can call two different ones.
