Next, send this message to the Whatabot account: “I allow whatabot to send me messages.” You can also register your WhatsApp number on this link.

The Whatabot contact number is +54 9 1123998026. To register your WhatsApp number with Whatabot API, create a Whatabot contact in your smartphone. To begin, register your WhatsaApp number or Telegram account with API via your smartphone. The API operates in real-time, communicating messages from a microcontroller to the smartphone of the user instantly. It’s an easy and excellent way to communicate messages to a registered number or Telegram account. Messages are communicated as HTTP GET requests from a microcontroller or an app.ĪPI is specifically designed for use with IoT devices and web applications. Whatabot is a third-party service that allows real-time messages to be sent via WhatsApp or Telegram. To communicate, you’ll also need a smartphone device with an active SIM and either the WhatsApp or Telegram app installed.

The cable is necessary to upload the sketch to the board from a host computer. What’s required is an ESP32/ESP8266 board and a MicroUSB cable. There are no circuit connections for this project. We are choosing ESP32 because it’s a WiFi development board and requires no extra components to connect with a WiFi access point. In this project, we’ll program an ESP32 board to directly communicate messages to a WhatsApp number or a Telegram account. So, what if these messages could be sent via the IoT to a user’s WhatsApp or Telegram account instead? But sometimes text messaging is unavailable between devices. Typically, text messages are sent via WiFi or SMS. In many Internet-of-Things (IoT) applications, it’s necessary to send alerts to the user in the form of messages.
