Client error in get availability by pincode

401 Client Error: Unauthorized for url: https://cdn-api.co-vin.in/api/v2/appointment/sessions/calendarByPin?pincode=700091&date=04-05-21

Error when get availability by pincode method is run

@AdityaMitra5102, the function call works fine for me. However, when I try the url you have pasted above, it does not work since there is a public missing as part of the url and also the date format should be 04-05-2021 (DD-MM-YYYY). Trying the following in the browser does return the correct result https://cdn-api.co-vin.in/api/v2/appointment/sessions/public/calendarByPin?pincode=700091&date=04-05-2021

@backtrackbaba, the url is probably incorrect in the constants file and worked for me maybe by chance. The correct url can be found here. Shall I create a pull request to update the line from

    availability_by_pin_code_url = f"{base_url}/appointment/sessions/calendarByPin"

to

    availability_by_pin_code_url = f"{base_url}/appointment/sessions/public/calendarByPin"

?

Yeah it would be better then

@AdityaMitra5102, I updated my comment above, your date format is also incorrect.. can you try rerunning with the correct date format ?
