Global Variables

The Global Variable Store holds persistent, user-scoped key-value data that survives across workflow executions. Use it for API keys, configuration, or shared state that multiple workflows need.

Local vs Global

Creating Global Variables

1. From the Variables tab – Variables Tab: Create, edit, and delete variables directly.
2. From a Variable node – Enable Store in Global Variable Store (isGlobal: true) in the node's properties. The variable is written to the store when the workflow runs.

Using in Expressions

Access global variables with $global.variableName:

$global.apiKey
$global.settings.baseUrl
$global.userId

Use the same methods as workflow-local variables (e.g. .upper(), .length, .add() for arrays).

Value Types

Supported types: string, number, boolean, array, object. Choose the type when creating or editing a variable.

Sharing Global Variables

You can share a global variable with other users or Teams so they can use it in their own workflows.

• Share with user – Click the share icon next to an owned variable, enter the recipient's email, and click Share. The recipient will see the variable in their Global Variables list with a Shared badge and a "Shared by <your email>" label.
• Share with team – In the share dialog, select a team and click Add. All team members gain access.
• Editable access – Recipients can view, edit, and reference the shared variable via $global.variableName in their workflows. Only the owner can share, unshare, or delete the variable.
• Name conflicts – If a recipient already has a variable with the same name, their own variable takes precedence over the shared one.
• Deshare – Open the share dialog for the variable and click the × button next to the user you want to remove access for.

Chat Integration

Global variables are available to the Chat assistant. The LLM can reference them when answering questions or generating content.
