Generate workflows from natural language using GPT-4o Mini and n8nBuilder API

🤖 AI-Powered n8n Workflow Generator with n8nBuilder API Overview This workflow lets you generate complete n8n workflows from natural language descriptions using the n8nBuilder API. 🚀 Users submit a short description via a form, and the workflow returns a ready-to-import n8n workflow JSON. Why use it? ⚡ AI-generated workflows from natural language 🛠️ Production-ready patterns (triggers, error handling, best practices) 🎯 Perfect for beginners who don't know which nodes to pick 🔄 Two modes: Form-based and AI Chat Agent --- Prerequisites 🔑 n8nBuilder account + API token — Get your free token at n8nbuilder.dev 🏢 An n8n instance (Cloud or self-hosted) 🤖 OpenAI API Key (Optional - to use with AI Agents) ⚠️ Important: Never expose your API key in public workflows. Use n8n Credentials for production setups. --- Setup Instructions Get your n8nBuilder API token Visit n8nbuilder.dev Sign up or log in to your account Navigate to Account → API to generate your token Configure the Form The Form Trigger collects: api_token (required) — Your n8nBuilder API token email (required) — Your email address query (required) — Natural language description of the workflow (e.g., "Read RSS from https://n8nbuilder.dev/blog/feed.xml every hour and send Slack message if new post arrives") Workflow Execution User fills the form and submits Workflow sends a POST request to https://api.n8nbuilder.dev/api/generate n8nBuilder API processes the request and generates a complete workflow Response is cleaned and formatted User receives the generated workflow JSON ready to import Outputs The workflow returns: output — Complete n8n workflow JSON ready to import 💡 Tip: Copy the generated JSON and import it directly into your n8n instance via Settings → Workflows → Import from File. --- Customization Tips 📝 Write clear descriptions: The more specific your query, the better the generated workflow 🎨 Try different use cases: Data transformation, API integrations, scheduled tasks, webhooks, etc. 🔧 Edit after generation: Generated workflows are production-ready but you can always customize them further 🤖 Use AI Chat mode: Enable the AI Agent for conversational workflow generation --- Alternative: Use the n8nBuilder Community Node 🎁 Optional: Install the n8n-nodes-n8nbuilder community node if you prefer using a dedicated node instead of raw HTTP. See: GitHub Repository --- Troubleshooting 401/403 Unauthorized → Check your API token in the form Invalid JSON → Ensure your email and query are properly filled No output returned → Verify your API token is valid and active Slow response → Complex workflows may take a few seconds to generate --- Security Best Practices 🔒 Do not hardcode API tokens in public workflows 🔐 Use n8n Credentials for storing tokens securely 🛡️ Keep your API token private and regenerate if compromised --- Learn More 📚 n8nBuilder Documentation
