How to use custom labels in the salesforce lightning screen flow

An explainer on how to use custom labels in the Salesforce lightning screen flow.

Custom labels are custom text values that can be accessed from Apex classes, Visualforce pages, Lightning Pages, or Lightning components. The values can be translated into any language Salesforce supports.

Create a custom label from Salesforce login > Setup > Custom labels > New

Lighting flow builder comes up with an option to include custom labels in different ways. Either you can directly add the custom label to the flow elements or create a formula field referring custom label and use it across elements of the flow.

Let us see that in action.  

Use custom labels in the flow elements (example text area element)

Log in to Salesforce > Go to Setup > Flows > Create a new Flow of type Screen Flow

Drag and drop screen element from the left pane to the canvas

Enter the Label (1), API Name (2), and Drag & drop Display Text from the components tab to the screen element (3)

Select Display text item component (1), fill API Name (2), click on the Insert a resource input search box (3), and type or select $Label (4)

Select the custom label created (type custom label name if you don’t find it in the initial list displayed)

Click Done

Save the changes, and run the flow.

Message from the custom label must be shown on the flow screen at the run time.

We can also map the custom label within the Formula variable and use it across the flow. More details are below.

Use a custom label in the formula field of the screen flow

Go to the Manager tab within the flow builder, Click New Resource

Select Formula in the drop-down

Update API Name, select a Data type, Click on Insert a resource input box, select $Label, and select or type your custom label name

A custom label is added to the formula field, click Done.

A formula field that refers to the custom label is available. Make use of it across the flow. 

Whenever there is a change in the message text from the business, we just need to update the custom label.
