Render Flows with Visualforce

Embed Flows in Visualforce Pages
To customize a flow’s look and feel or enhance its functionality, embed it in a Visualforce page. If your org has flows enabled for sites and portals, use the Visualforce page to deliver the flow to your Salesforce site, portal, or Experience Cloud site.

An Advanced Example of Using <flow:interview>
The <flow:interview> component is designed to make it easy to develop complex Visualforce interactions. You can access additional features in your flow by creating a custom controller. With custom controllers, you can build a page with multiple components that can interact with each other. Any flow within your organization can be individually referenced by its own Apex type, and the variables in the flow can be accessed as member variables.

Set Flow Variable Values from a Visualforce Page
After you embed your flow in a Visualforce page, set the initial values of variables, record variables, collection variables, and record collection variables through the <apex:param> component.

Get Flow Variable Values to a Visualforce Page
Flow variable values can be displayed in a Visualforce page. Once you’ve embedded your flow in a Visualforce page, you can use Visualforce markup to get values for variables or record variables. To display values for a collection variable or a record collection variable, you can use Visualforce markup to get the individual values contained in the collection.

Control Whether Users Can Pause a Flow from a Visualforce Page
After you embed a flow in a Visualforce page with the <flow:interview> component, consider whether you want to let users pause flows from that page. Set the allowShowPause attribute to false to prevent users from pausing.

Customize How Users Resume Paused Flow Interviews
By default, users can resume their paused interviews from the Paused Interviews component on their home page. If you want to customize how and where users can resume their interviews, use the pausedInterviewId attribute on the <flow:interview> component.

Configure the finishLocation Attribute in a Flow
If finishLocation isn’t specified, users who click Finish start a new interview and see the first screen of the flow. You can shape what happens when a user clicks Finish on the final screen by using the URLFOR function, the $Page variable, or a controller.

Customize a Flow’s User Interface
After you’ve embedded a flow in a Visualforce page, you can customize what the flow looks like at run time by applying custom styles using CSS. Using a combination of flow attributes and CSS classes, you can customize the individual parts of a flow, such as the button location, button style, background, and the look and feel of the screen labels.

Render Lightning Runtime for Flows in a Visualforce Page
By default, when you embed a flow in a Visualforce page, the flow renders in Classic runtime. Like its name suggests, Classic runtime looks and feels like regular Visualforce pages and the Salesforce Classic desktop experience. To render a flow in Lightning runtime, add the lightning:flow Aura component to your Visualforce page.
