# Is Empty

The *Is Empty* action node allows the workflow to verify whether a user-input variable (or the response returned via an [*API Integration*](/flow/action-nodes/action-nodes-api-integration.md) node) is empty or not. 

You can define what action should follow in each case - either route the customer to a specific step in the workflow, or trigger another workflow.
