Explainer

A Visualforce page can run a flow by embedding a Flow interview in the page, so a developer can present that flow inside custom page markup. The usual component is flow:interview: you name the flow, optionally bind a controller handle to the interview, pass starting values in, and display values from the interview on the page. By default the embed uses Classic runtime; Lightning runtime is a separate path that places the lightning:flow Aura component on the page.

Core information
  • The flow:interview component embeds a Flow interview in a Visualforce page. Its required name attribute is the unique name of the flow.
More details and nuances
  • You can set variables only at the beginning of an interview. If you reference a variable that does not allow input access, attempts to set it are ignored, and compilation can fail for the Visualforce page, its apex:page component, or the Apex class. The same ignore-or-fail behavior applies when you try to get a variable that does not allow output access.
