I was just trying to make covid vaccine alert using Cowin Setu API (India) in nodejs. But I am facing some strange thing, whenever I hit get request I got 403 response code from cloudfront says 'Request Blocked' but the same is working from postman as well as from browser. Please help me in this
Getting this error:-

I hope this problem will solve

When you encounter this error message, you are basically trying to reach an address or a website that is forbidden to access. Here are examples of some these errors that are commonly thrown: Forbidden: You don't have permission to access [directory] on this server HTTP Error 403 – Forbidden
Since the error 403 forbidden is closely related to file access permissions, it will be the main focus of the following methods to fix it. That said, there are other ways of resolving this issue, such as clearing the web browser cache or scanning for malware.
Now if you want to deploy to Heroku or firebase, then it will return 403, I think it's mostly that they are blocking any IP hit outside from Indian server. Thanks for contributing an answer to Stack Overflow!
Show activity on this post. These will not work in production because Cowin APIs are geofenced and can't be accessed from IP address other than Indian. In most free hosting sites like Heroku, Indian IP is not an option. So alternative solution might be to use AWS, GCP, Azure with an Indian server (not tried yet).
Try These Headers They worked for me on local server (not production)
let options = {
headers: {
"user-agent":
"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.93 Safari/537.36",
},
};

I added a user-agent header to the request so that the API would recognize that my request is coming from a browser, rather than a script.
headers = {
'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36',
}
url = "https://cdn-api.co-vin.in/api/v2/appointment/sessions/public/calendarByDistrict?district_id=303&date="+date
response = requests.get(url, headers=headers)
Use following
var options = {
url: URL,
method: 'GET',
headers: {
Host: 'cdn-api.co-vin.in',
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.93 Safari/537.36'
}
};
