cowin book backup

cowin_auto_book.js

// This is WIP (Work in Progress) and this doesn't work, auto booking is still not tested properly. Use the last file cowin_schedule_v2.js
// If you want use the 3rd file in the list which will alert you as soon as a slot opens up
// This script tries to automatically book a slot from the list of pincodes given.
// It will book the first available slot.
// You can get the beneficiary ID from your networks tab when the dashboard loads
// Please do change the date to which ever day you are searching for. (Works only for a few days in advance)

auto book script is giving unauthorized access error response. How do i fix it?

qq:https://cdn-api.co-vin.in/api/v2/appointment/schedule does this API work without authentication?

@reddivari9 Auto book is not developed. Right now working on a chrome extension for alerting. Once that is done will look into auto book
@abhishek1234321 no it doesn't. This script was written for the scenario that user is logged into self registration website.

some error

pls help
