How to send WhatsApp Messages from MS Flow

It is very simple to send WhatsApp messages from your MS Flow Automation. You just need to use the HTTP Action

1) Get an APIkey using the instructions described above

2) Add an "HTTP" Action into your MS Flow

3) Complete the HTTP configuration as shown below

What is key in the configuration is to format the "Subscribe URI" properly. The "text" field must be urlencoded and it can be dynamically created to send different messages using MS Flow variables for example.

Format of the URI field:

https://api.callmebot.com/whatsapp.php?phone=<your_phone_number>&text=<text_message_to_send>&apikey=<your_apikey>

Problems?

If you have problems, like not receiving the Call on Telegram, or not receiving the WhatsApp messages,  try to test the CallMeBot API using your Web Browser:

  • Telegram Phone Calls using Web Browser: here
  • Telegram Text Messages using Web Browsers: here
  • WhatsApp Text Messages using Web Browser: here

You might get some errors on the screen that will help you to identify the problem. (Ex: Calls disabled in the Telegram Security Settings, WhatsApp not activated, etc.)
