CallMeBot: Sending Alerts to Various Messaging Apps using APi

At multiple ISP’s or networks, I use either GSM Modems or 3rd party SMS API to send various information / alerts messages to admin or users , & it involves minor cost on a per sms basis or as bundle. Another method to send messages on WHATSAPP & its FREE , very simple to use CALLMEBOT APi’s. Its a online FREE service via which you can send basic messages to multiple messaging services like WhatsApp / messenger / Signal / Telegram apps.  The only caveat is that you cannot send messages to EVERY contact. The receiver contact must have the callmebot API KEY , which he can easily get via adding callmebot number in there contact list & send particular message & he will get it instantly. so EACH API EKY is tagged with that particular mobile number only. Once you know the key & its tagged mobile number, you can send message to that contact using the API_KEY & his mobile number using various methods.

In this guide we will be using callmebot API to send various test message to admin WhatsAPP number. Follow the below steps …

• First, You need to get the API key form the CallMeBot. Add the phone number +34 644 91 96 80 into your Phone Contacts. (Name it it as you wish like CallMeBoT / My_Alerts etc )
• Using WhatsApp, Send this message to this contact

I allow callmebot to send me messages

• once it is sent, Wait until you receive the message like “API Activated for your phone number. Your APIKEY is XXXXXX” from the bot. Note down the APIKEY
  Note: If you don’t receive the ApiKey in 2 minutes, please try again after 24hs.
• The WhatsApp message from the CallMeBot will contain the API key needed to send messages using various API.
• Now You can send text messages using the API after receiving the confirmation.
