Description
Make your voice agents more intelligent and personalized by dynamically inserting user-specific data from Google Sheets using this n8n workflow. Built for Retell AI, this integration allows voice agents to greet callers with context-rich, customized responses based on their phone number.
🔹 How It Works:
✅ 📞 Receive Inbound Call Webhook – Retell sends a webhook to n8n when someone calls your number ✅ 🔍 Match Caller – The workflow extracts the caller’s phone number and searches your Google Sheet for a matching entry ✅ 📄 Retrieve Variables – Pulls all relevant user data associated with that number ✅ 🧠 Format & Respond – Formats the data into key-value pairs and returns them to Retell to populate the dynamic variables ✅ 💬 Real-Time Personalization – Retell dynamically replaces placeholders in prompts (like {{first_name}}) with the returned values
🧑💼 Who Is This For:
✅ Retell AI Voice Agent builders ✅ AI support and onboarding teams ✅ Developers building voice-enabled workflows ✅ Sales or customer support teams seeking phone-based personalization
🚀 Why Use This Workflow:
✅ Personalizes every voice interaction with live data ✅ Makes your Retell agents smarter without touching the voice script ✅ Supports flexible backend sources (swap Google Sheets for Postgres, Airtable, etc.) ✅ Fully automated—just add new numbers and data to the sheet
🎯 Bring Context to Every Call Empower your AI voice agents to speak with context—instantly and automatically. This simple yet powerful automation creates a better, more human voice experience with every interaction.
