Automate WhatsApp Group Messaging with VBA

Looking to integrate WhatsApp group messaging into your Microsoft Office applications? This guide walks you through sending WhatsApp group messages using Visual Basic for Applications (VBA) and the WhatsMate WA Gateway REST API. Perfect for Excel, Access, Word, or any Microsoft Office automation that needs WhatsApp group notifications.

đź“‹ Prerequisites

Before you begin, ensure you have:

  1. A WhatsMate WA Gateway Forever Green account - Required for group messaging API access
  2. Group setup - Create a WhatsApp group with a unique name and add the gateway
  3. Microsoft Office application - Excel, Access, Word, or other Office app with VBA support
  4. VBA editor access - Enabled developer mode in your Office application
  5. Basic VBA knowledge - Familiarity with Visual Basic for Applications syntax

⚠️ Important: You need a Forever Green account to send messages to WhatsApp groups. The gateway must be added to your WhatsApp group before it can send messages. Sign up for a Forever Green account to enable group messaging capabilities.

đź“ť Step-by-Step Implementation

Follow these steps to send your first WhatsApp group message from a VBA application:

1. Prepare Your WhatsApp Group

Before coding, set up your WhatsApp group:

  1. Create a new group in WhatsApp with a unique name (the API won’t work if the name isn’t unique)
  2. Add the secret gateway number to the group
  3. Send a “Hi” message (or any message) in the group from your personal WhatsApp account - this helps the gateway silently recognize the new group in the background

2. Copy the VBA Template

In your Excel, Access, or VBA development environment, define the following subroutines:

3. Configure Key Parameters

Customize these essential parameters in the VBA program:

  • Line 2: Specify the group admin’s phone number (including country code, e.g., 12025550108)
  • Line 3: Provide your group name (must be unique)
  • Line 4: Enter your message content
  • Line 17: Replace YOUR_INSTANCE_ID_HERE with your WhatsApp gateway instance ID
  • Lines 18-19: Update YOUR_CLIENT_ID_HERE and YOUR_CLIENT_SECRET_HERE with your Forever Green Client ID and Secret

4. Run the Macro

  1. Open the VBA editor in your Office application (Alt + F11)
  2. Paste the code into a module
  3. Run the Main_Routine macro to send your WhatsApp group message

🔧 Common Use Cases

This VBA integration is ideal for:

  • Excel automation - Send WhatsApp group notifications based on spreadsheet data or calculations
  • Access database workflows - Trigger WhatsApp messages from database events or record updates
  • Office document automation - Automate WhatsApp communications from Word documents or PowerPoint presentations
  • Business process automation - Integrate WhatsApp group messaging into existing Office-based business workflows
