Variables

n8n provides built-in variables for working with data. This document provides a reference list of available variables, with a short description, and whether they're available in the expressions editor, Function node, or both.

For usage examples, refer to Expressions examples - Variables and JavaScript examples - Variables.

Method	Description	Availability
$binary	Shorthand for $input.item.binary. Incoming binary data from a node	Expressions editor
$data	Incoming raw data from a node.	Both
$env	Contains environment variables.	Both
$execution.id		Both
$execution.mode		Both
$execution.resumeUrl	The webhook URL to call to resume a waiting workflow.	Both
$json	Shorthand for $input.item.json. Incoming JSON data from a node	Expressions editor
$now	A Luxon object containing the current timestamp. Equivalent to DateTime.now().	Both
$parameters	Parameters of the current node.
$position	The index of an item in a list of itemd.
$prevNode.name	Note that $prevNode always takes the first input. This is important when using it in a node with multiple inputs, such as the Merge node.	Both
$prevNode.outputIndex	Note that $prevNode always takes the first input. This is important when using it in a node with multiple inputs, such as the Merge node.	Both
$prevNode.runIndex	Note that $prevNode always takes the first input. This is important when using it in a node with multiple inputs, such as the Merge node.	Both
$runIndex	How many times n8n has executed the node. Zero-based (the first run is 0, the second is 1, and so on).	Both
$today	A Luxon object containing the current timestamp, rounded down to the day. Equivalent to DateTime.now().set({ hour: 0, minute: 0, second: 0, millisecond: 0 }).	Both
$workflow.active		Both
$workflow.id		Both
$workflow.name		Both
