Signal or WhatsApp Messenger

Hello forum members

I'm looking for an application that uses either Signal or WhatsApp Messenger for communication.
Who has a source for a trustworthy, working and practical solution for this?

Hello Paul

This is practical and easy to implement solution:

Using this free non official WhatsApp API:
https://textmebot.com/

There are examples for both ESP8266 (ESP01) and ESP32, modules with WiFi connection.

As easy as send a GET request with your APY_Key and your Text message:

https://api.textmebot.com/send.php?recipient=[phone number]&apikey=[your  apikey]&text=[text to send]

Check the API help:
https://textmebot.com/send-text-messages/

Regards
JL
