⚡ n8n Automation Skill

Overview

This skill connects your OpenClaw agent directly to your n8n instance so you can trigger powerful multi-step automations using plain natural language — no coding required at runtime.

What makes this skill different: It does not just call webhooks. It confirms before acting, validates inputs, reports results, handles errors gracefully, and remembers what was last triggered so you can easily repeat or modify runs.

Setup (One Time)

Before using this skill, export these two environment variables in your terminal or add them to your shell profile:

export N8N_WEBHOOK_BASE_URL="https://your-n8n-instance.com/webhook"
export N8N_API_KEY="your-n8n-api-key-here"

Then restart your OpenClaw gateway:

openclaw gateway restart

You will know setup worked when you type:

"n8n status"

And the agent responds with your instance URL confirmed.

Trigger Phrases

You can trigger this skill with any of these natural language phrases:

  • "trigger n8n [workflow name]"
  • "run automation for [contact/task]"
  • "send [email type] to [name]"
  • "post to social: [content]"
  • "update CRM for [name]"
  • "follow up with [name] from [meeting]"
  • "check competitors"
  • "send invoice reminder to [client]"

Error Handling

If any webhook call fails, follow this sequence:

  1. Report the error clearly: "The [workflow name] webhook returned [error]. Here is what was sent: [payload summary]"
  2. Ask: "Should I retry, or would you like to check your n8n instance?"
  3. Do NOT silently fail or pretend the workflow ran
  4. Log the failed attempt in memory: "Failed workflow: [name] at [timestamp] — Error: [message]"

Rules (Always Follow These)

  • ALWAYS confirm what you are about to trigger before sending
  • NEVER expose API keys, webhook URLs, or credentials in chat
  • NEVER trigger a workflow without all required fields
  • If a required field is missing, ask for it before proceeding
  • NEVER send test data to production webhooks unless user confirms
  • Always report the n8n response status back to the user
  • If triggering email workflows, confirm the recipient email address out loud before sending
  • Log every successful trigger to daily memory: "[Workflow] triggered for [target] at [time]"

Status Check

At any time the user can type "n8n status" and you should:

  1. Run: python3 scripts/n8n_status.py
  2. Display the output exactly as returned
  3. If any workflows show as inactive, suggest running: python3 scripts/n8n_validator.py

Scripts Reference

All scripts live in the scripts/ folder and use only environment variables — no secrets stored in files.
