Local Actions are a new kind of Lightning Flow node type. They appear in the Cloud Flow Designer and can be added to Flows.
Local Actions execute like regular flow elements, but they do so on your computer, leveraging Lightning Components. Like Lightning Components, Local Actions can interact with your computer and make flexible connections to the web.
Local Actions is a open pilot feature. That means that the feature is likely to change and may not become a Generally Available feature. To get access to this pilot, contact customer support and request that they enable you for the Local Actions pilot.
