Connect HelloLeo to your n8n instance to trigger workflows, execute automations, and integrate with your n8n workflows.

​
Setup

  1. Go to Project Settings → Project Integrations
  2. Select n8n from the list
  3. Enter your credentials:
    • API Url - Your n8n instance API URL (e.g., https://your-n8n-instance.com)
    • API Key - Your n8n API key
  4. Test the connection
  5. Start using n8n in your prompts

​
How It Works

HelloLeo connects to your n8n instance using the n8n API. Your API URL and API key are encrypted and stored securely on the backend.

​
Common Operations

With n8n integration, you can:
  • Trigger workflows - Execute n8n workflows programmatically
  • Manage workflows - Create, update, and manage workflow definitions
  • Monitor executions - Check workflow execution status and results
  • Handle webhooks - Work with n8n webhook nodes
  • Automate tasks - Integrate n8n automations into your applications

​

​
Best Practices

  • Specify workflow names - Always mention which n8n workflow you want to use
  • Mention the integration - Always say “from n8n” or “to n8n” so Leo knows which integration to use
  • Workflow parameters - Clearly specify any parameters your workflows need
  • Error handling - Consider how to handle workflow execution errors

​
Troubleshooting

​
Connection Issues

  • Check API URL - Verify your n8n instance URL is correct and accessible
  • Check API key - Ensure your n8n API key is valid
  • Network access - Verify your n8n instance is accessible from the internet (if needed)

​
Workflow Not Triggering

  • Workflow name - Verify the workflow name or ID is correct
  • Workflow status - Ensure the workflow is active
  • API permissions - Check that your API key has permission to execute workflows

​
Execution Errors

  • Workflow configuration - Review workflow node configurations
  • Parameters - Verify all required parameters are provided
  • Logs - Check n8n execution logs for detailed error messages
