OpenClaw + n8n Webhook Tutorial: Collect YouTube Metadata with an AI Agent
In this week's tutorial, we demonstrate how to connect your OpenClaw AI agent to an n8n automation workflow using a Webhook. Learn how to securely extract YouTube video metadata without ever exposing your API keys to the LLM!
By decoupling the reasoning engine (OpenClaw via Telegram) from the execution engine (n8n on a Google Cloud VM), we create a highly secure, scalable, and mobile-friendly automation pipeline. You can trigger complex automations right from your phone while keeping all the logic and credentials safely stored in n8n.

💡 Key Takeaways:
Security: Keep API keys in n8n credentials, not in your agent's scripts.
Efficiency: Use n8n to clean massive JSON payloads so your LLM uses fewer tokens.
Flexibility: Trigger complex automations from anywhere using Telegram.
