About This Workflow
Overview
This n8n workflow demonstrates how an AI agent can leverage a custom sub-workflow to handle specific tasks. In this case, the sub-workflow checks if a user has provided an email address. If an email is missing, it prompts the user to include it in their next message and informs them that a human will be contacted for assistance. If an email is present, it messages a Slack channel for help.
