Whatsapp Bot for CoWIN vaccination (with automated CAPTCHA verification)

This is absolutely for academic reference purposes only. Lagalities arising out of commercial or personal use is none of the concerns of the author(s) of this and/or any related repo

On your computer whatever number you logged in to WhatsApp with, by scanning the QR code, that number becomes the host. Any other mobile number who want to book, will need to send subscribe to the host whatsapp. After that, the bot will ask all the details it needs and begin polling the cowin server. When a slot is available, it will notify via whatsapp to the subscriber, send OTP and read CAPTCHA on its own before going ahead with booking. If the host wants to book for oneself, the host will also need to send subscribe message to itself.
