Send Return Pickup Reminders via WhatsApp & Voice Calls using Google Sheets

✅ What problem does this workflow solve?

Missed return pickups create logistics delays, extra follow-ups, and unhappy customers for e-commerce teams. This workflow automates return pickup reminders, ensuring customers are notified on the day of pickup via WhatsApp messages and automated voice calls, without any manual effort.

⚙️ What does this workflow do?

Runs automatically on a daily schedule. Reads return pickup data from Google Sheets. Identifies customers with: 📅 Pickup date = today ⏳ Status = Pending Sends personalized WhatsApp reminders. Places automated voice call reminders when required. Updates reminder status in Google Sheets for clear tracking.

🧠 How It Works – Step by Step

1. ⏰ Scheduled Trigger The workflow starts at a fixed time every day (e.g., 9–10 AM) using a Schedule Trigger.

2. 📄 Read Pickup Data from Google Sheets It fetches rows from Google Sheets where: Pickup Date** = today Status** = Pending

This ensures only relevant pickups are processed.

3. 🔁 Loop Through Pickups Each matching row is processed individually to send customer-specific reminders.

4. ✍️ Generate Personalized Messages Using a Code node, the workflow creates: 📲 A WhatsApp text message 📞 A voice message script

Messages include: Customer name Product name Pickup address Return reason Pickup timing reminder

5. 📲 Send WhatsApp Reminder A personalized WhatsApp message is sent via Twilio, reminding the customer to keep the package ready.

6. 📞 Place Voice Call Reminder If required, the workflow places an automated voice call using Twilio and reads out a clear pickup reminder using text-to-speech.

7. ✅ Update Pickup Status Once notifications are sent: The workflow updates the Status column to “Reminder Sent” Ensures the same pickup is not notified again
