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
