Replace line #51, in the original code, with following:
if (a.centers[c].sessions[s].vaccine === "COVAXIN" && a.centers[c].sessions[s].available_capacity_dose2 > 0 && a.centers[c].sessions[s].min_age_limit < 45) {

Hey y'all, just saw this! I actually have a really comprehensive script with just a few setup instructions you can immediately run through and setup, with completely functional auto booking, just that you need OTP and captchas entered manually, but it still is really handy!

Hi,
what is cowin_whitelist_center_ids ? is it pincode of center ?

Hi there @newreddy, those are for which centers you want to explicitly want to only book slots from, and those can be found by going to the url similar to: https://cdn-api.co-vin.in/api/v2/appointment/sessions/calendarByDistrict?district_id=DISTRICT_NUMBER&date=DD-MM-YYYY where DISTRICT_NUMBER is the number you determine following steps in the README and the date formatted per the format shown in the aforementioned url. In there, you'll see each center in that district, and you can whitelist specific ones, or just leave that environment variable blank to book slots from any center

Yeah so that means there are no slots currently available for COVAXIN appointments. If you provided COVAXIN in vaccine type and are trying to book then when those slots open it’ll prompt you for captcha and register immediately!

Hello @newreddy, you can actually pull from the repository as I have now automated the captcha portion, thanks to https://github.com/sushrut111/cowin-automation-extn, especially @ayushchd
All you need to worry about is getting OTP now, and I will be pushing up some steps in the README to also automate the OTPs
