Posted on Nov 10, 2025 • Edited on Nov 10, 2025. Task: Posted on Nov 10, 2025 • Edited on Nov 10, 2025 I recently built an end-to-end appointment reminder workflow using n8n that helps businesses ensure customers never miss their scheduled meetings. Here’s how it works: ✅ Daily Trigger: Executes every morning ✅ Calendar Integration: Fetches the day’s appointments from Google Calendar ✅ Voice Reminder: Places an automated call via Retell AI to remind the customer ✅ Follow-up SMS: Sends a personalized message using Twilio after a short delay This workflow saves valuable time, improves communication consistency, and delivers a seamless reminder experience — all without human intervention. Always fascinating to see how automation and AI can streamline everyday operations so elegantly. ⚙️🤖 Top comments (0) For further actions, you may consider blocking this person and/or reporting abuse; tools: n8n.

Try it
Act as an automation engineer. I need to build an appointment reminder system using n8n. Inputs: [Google Calendar ID], [Retell AI API Key], [Twilio SID/Token], [Test Customer Phone]. Steps: 1. Create a daily trigger. 2. Fetch today's events. 3. For each event, call Retell AI for voice reminder. 4. Wait 5 minutes, then send Twilio SMS. 5. Log results. Deliverable: A JSON export of the n8n workflow. Quality Check: Run a dry run with one test appointment. Verify logs show successful API responses. Do not deploy to production until I confirm the dry run output. If API keys are missing, ask for them before proceeding.
