(Bot with captcha solving & alerting capabilities. Never miss the vaccine slot.)


  • Your computer will act as a server to update messages & recieve messages from telegram bot.
  • This automation script, gathers the recieved messages from the user & checks the details on COWIN portal.
  • Your phone (Telegram app) will act as a client to recieve messages sent from the computer.
  • If your computer stops or your script stops on computer, you will not see any updates on telegram, neither it will search for any slots.
  • You need to constantly respond if you recieve any alerts on telegram as notification.

Personally, we have used this & we (me, Srishti) got vaccinated, hope it helps you as well.

This automation subscribes to the telegram bot. Once registered mobile number is entered, it gets the cowin-session using otp provided by the user. While maintaining the valid user session, it tries to find a vaccination slot for the selected user & selected calendar. It checks for preferences such as vaccine type, state, pincode, district, paid/free & whether to auto-book the slot or not. Once slot is found, it tries booking it by randomly selecting the slot & resolving the captcha.
