Lesson25- how to send alert message to Whatsapp by KC868-A4 A8 (ESP32)

[Sophia78]

To send an alert message to WhatsApp using the KC868-A4 A8 (ESP32), you can use the Twilio API to programmatically send SMS messages, including WhatsApp messages. Here is an example workflow:

1. Sign up for a Twilio account and get a Twilio phone number.
   
2. Set up a new project in Twilio to receive SMS messages.
   
3. Use the Twilio API to send a message to a specific phone number in the format "WhatsApp:<phone-number>".
   
4. Use the ESP32 to make an HTTP request to the Twilio API, passing in the message and destination phone number.
   

You will need to have some experience with programming and APIs to complete this task. Additionally, you may need to consider purchasing a Twilio package to access the API.
