How to Automate Patient Appointment Reminders via WhatsApp Using Google Sheets (No Coding Needed)

Missed patient appointments are one of the most common challenges faced by healthcare professionals across India. Whether you run a small dental clinic, a physiotherapy center, or a large hospital, manually tracking and reminding patients about appointments can be time-consuming and prone to human error.

Here’s the good news — you can now automate WhatsApp reminders directly from Google Sheets using WhatsBoost, India’s most advanced WhatsApp automation platform for healthcare and small businesses.

In this step-by-step guide, you’ll learn how to send automated WhatsApp reminders to patients directly from Google Sheets — no coding, no complex tools, and full control at your fingertips.

Why Automate Appointment Reminders on WhatsApp?

Before we jump into the setup, let’s understand why automation matters for healthcare communication.

• Reduce No-Shows: Automated reminders help ensure patients remember their scheduled visits.

• Save Time: Eliminate the need for manual calls and follow-ups.

• Enhance Communication: WhatsApp provides instant, direct, and personalized messaging.

• Improve Patient Experience: Timely updates help build reliability and trust.

• Gain Insights: Track confirmations, cancellations, and reschedules in real time.

Studies show that clinics using automated WhatsApp reminders have seen up to a 40% reduction in appointment no-shows.

What You’ll Need to Get Started

To automate WhatsApp reminders using WhatsBoost and Google Sheets, you’ll need the following:

✅ A Google Sheet with columns for:

• Patient Name

• Contact Number

• Appointment Date

• Appointment Time

• Reminder Status

✅ A WhatsBoost Account (Sign up at WhatsBoost.in)
✅ Your WhatsBoost API Key
✅ Access to Google Apps Script (built into Google Sheets)

How the Automation Works

The process is straightforward:

1. You add or update patient details in your Google Sheet.

2. The WhatsBoost system checks the sheet regularly.

3. When the scheduled time arrives, a personalized WhatsApp reminder is automatically sent to the patient.

The message might look like this:

“Hi [Name], this is a reminder for your appointment on [Date] at [Time]. Please reply ‘Confirm’ or ‘Reschedule’ if you need to make any changes.”

Step-by-Step Setup: Sending WhatsApp Reminders from Google Sheets

Step 1: Create and Format Your Google Sheet

Start by creating a new Google Sheet with these columns:

• Patient Name

• Contact Number

• Appointment Date

• Appointment Time

• Reminder Status

This sheet will serve as your mini patient management dashboard.

Step 2: Generate Your WhatsBoost API Key

1. Log in to your WhatsBoost account at WhatsBoost.in.

2. Go to API Settings → Generate API Key.

3. Copy the key — you’ll need it in the script below.

Step 3: Add the Automation Script

1. In Google Sheets, go to Extensions → Apps Script.

2. Paste the following code:

function sendWhatsAppReminders() {
  const sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  const data = sheet.getDataRange().getValues();
  const apiUrl = "https://api.whatsboost.in/sendMessage";
  const apiKey = "YOUR_WHATSBOOST_API_KEY";

  for (let i = 1; i < data.length; i++) {
    let name = data[i][0];
    let number = data[i][1];
    let date = new Date(data[i][2]);
    let time = data[i][3];
    let status = data[i][4];

    let now = new Date();
    if (status !== "Sent" && now >= date) {
      let message = `Hi ${name}, this is a reminder for your appointment on ${date.toDateString()} at ${time}. Please reply 'Confirm' or 'Reschedule'.`;

      let payload = {
        api_key: apiKey,
        phone_number: number,
        message: message
      };

      UrlFetchApp.fetch(apiUrl, {
        method: "post",
        contentType: "application/json",
        payload: JSON.stringify(payload)
      });

      sheet.getRange(i + 1, 5).setValue("Sent");
    }
  }
}

👉 Replace "YOUR_WHATSBOOST_API_KEY" with your actual key.

Step 4: Automate the Trigger

1. In the Apps Script editor, → Add Trigger.

2. Select the sendWhatsAppReminders function.

This will automatically scan your sheet and send messages at the appropriate time.

Step 5: Test the Automation

Try adding a sample entry to your sheet.
If everything is set up correctly, WhatsBoost will send the WhatsApp reminder, and the Reminder Status column will update to “Sent.”
