This article shows you how to send a document (e.g. a PDF file, an MP4 file, a WAV file, etc.) to a registered WhatsApp user in VBA / Visual Basic Script.

Before the recipient can receive your WhatsApp message, she MUST register with the WhatsMate WA Gateway. Instructions are available on the official site. Unregistered users will never receive messages from the Gateway.

To send a WhatsApp message containing a PDF document in VBA, do this:

  1. First, learn how to send a simple text message on the official site.
  2. With the above knowledge, you can now download our sample code.
  3. Locate the file vba/SendDocument.vbs.
  4. Study the VBA source code and customize the TODO/FIXME lines.
    • Among other things, put down YOUR OWN number as the recipient. You can’t send messages to strangers because we are against SPAMMERS.
  5. Copy the image assets\subwaymap.pdf in the sample code package to C:\Users\Public\subwaymap.pdf
  6. Run Main_Routine in the VBA program.

Happy coding :)
