Pull data from an on-premises or private cloud database directly into your flow without
going through the Salesforce server. Or do things directly in the browser, such as open a
particular URL or confirm that a record was created with a toast message. With flow local
means you can integrate directly with the browser. This feature is new in both Lightning Experience
and Salesforce Classic. However, it’s
supported only in Lightning flow runtime.
When you create a Lightning component that implements the flowruntime:availableForFlowLocalActions interface, the component appears in the
return control to the flow, in the invoke method use the
callback function that’s provided by the interface.
