Template Expressions

} syntax in node settings.', }

Some Workflow Builder node settings support template expressions: a way to insert dynamic values directly into text fields using {{ }} syntax. Instead of entering a static value, you reference submission data, system values, or global variables that are resolved at runtime.

Syntax

Template expressions use double curly braces around a variable name:

{{ variableName }}

You can embed expressions in a larger string:

Hello {{ data.firstName }}, your submission ID is {{ submissionId }}.

Available Variables

Submission Data

Access any field value from the current submission using its Property ID.

Expression	Description
`{{ data.propertyId }}`	The value of the field with the given Property ID.

Example: If a Text Field component has the Property ID emailAddress, use {{ data.emailAddress }} to reference its value.

System Variables

Expression	Description
`{{ submissionId }}`	The unique ID of the current submission.
`{{ userId }}`	The ID of the end-user associated with the current submission.
`{{ currentUser.property }}`	Properties from the authenticated user's session. See currentUser Object for available properties.

Global Variables

Global variables configured in the environment are accessed using the vars prefix.

Expression	Description
`{{ vars.variableName }}`	The value of a by name.

Where Template Expressions Are Supported

Not all node settings support template expressions. Settings that do are noted in their reference pages. Common examples include:

Node	Setting	Example
Task	Label	`task-{{ data.caseNumber }}`
Task	Back Button Label	`{{ data.previousLabel }}`
Task	Next Button Label	`{{ data.nextLabel }}`
Sub-Process	Label	`subprocess-{{ data.number }}`
Message	To	`{{ data.recipientEmail }}`
Message	Refer String Redirect Target	`workflow/path/submission/{{ submissionId }}`

Notes

Template expressions are processed on the server.
If a referenced variable is null or undefined, the expression outputs nothing by default. Depending on your environment configuration, it may an error instead.
Use plain text for fields that don't support expressions. Not all settings accept template expressions.
