Send WhatsApp Messages with a Google Sheets Function

You will need to make use of the Twilio API in order to send WhatsApp messages by utilizing a function within Google Sheets. Twilio offers a programmable messaging service that can be used to send messages to WhatsApp numbers. You can use this service to communicate with your contacts.

The following is an illustration of one method for configuring a custom function in Google Sheets so that it can send messages using WhatsApp by utilizing Twilio:

1. Visit the website https://www.twilio.com/whatsapp to create an account with Twilio.
2. When you’ve established a Twilio account, the next step is to get an Account SID and an Auth Token. After login in to the Twilio Console, you will see these credentials shown on the dashboard of the application.
3. Open your Google Sheets document.
4. From the main menu’s “Extensions” drop-down menu, select “Apps Script.” The editor for Google Apps Script will open when you click this.
5. In the editor, replace the code that is already there with the code shown below:

function SEND_WHATSAPP_MESSAGE(phoneNumber, message) {
  var accountSid = 'YOUR_TWILIO_ACCOUNT_SID';
  var authToken = 'YOUR_TWILIO_AUTH_TOKEN';
  var twilioNumber = 'YOUR_TWILIO_PHONE_NUMBER';
  
  var payload = {
    'To': 'whatsapp:' + phoneNumber,
    'From': 'whatsapp:' + twilioNumber,
    'Body': message
  };
  
  var options = {
    'method' : 'post',
    'payload' : payload
  };
  
  var url = 'https://api.twilio.com/2010-04-01/Accounts/' + accountSid + '/Messages.json';
  var response = UrlFetchApp.fetch(url, options);
  
  return response.getContentText();
}

1. Using your actual Twilio account SID, auth token, and Twilio phone number, replace the placeholders ”YOUR_TWILIO_ACCOUNT_SID”, ”YOUR_TWILIO_AUTH_TOKEN”, and ”YOUR_TWILIO_PHONE_NUMBER” in the code.
2. To save the script, either click on the icon that looks like a floppy disk or hit the ‘Ctrl + S’ combination on your keyboard.
3. Exit the script editor and save your changes.
4. In the document that you have created using Google Sheets, insert the phone number in one of the cells, and the message in another.
5. In a new cell, insert the following formula, replacing ‘A1’ and ‘B1’ with the cell references that correspond to the phone number and the message, respectively:

=SEND_WHATSAPP_MESSAGE(A1, B1)

1. To carry out the calculation, press the Enter key. The WhatsApp message will be sent using Twilio, and the function will then display the response in the appropriate cell.

Be certain that your sheet have the appropriate permissions to access any external APIs. In the event that you come across any errors, you should consult the documentation provided by Twilio and Google Sheets or seek the advice of a developer.

Remember to use this function in a responsible manner and in accordance with the terms of service established by Twilio as well as the policies established by WhatsApp.
