I am able to integrate RazorPay in my application. After successful payment I am trying to call RazorPay REST API fetchPayment to get the complete detail of transaction but facing below error.
Access to XMLHttpRequest at 'https://api.razorpay.com/v1/payments/pay_Fxxxxxxxxx' from origin 'http://localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status.
I tried with passing 'Access-Control-Allow-Origin': '*' in header but still not working.

It took me awhile to realized it's not a CORS issue. I have Cognito authorizer setup with my API Gateway. I test with the my IDtoken using Postman, when the authorizer on my header is incorrect or the token is expired, postman response would tell me
{
"message": "Unauthorized"
}
{
"message": "Token expired"
}
The problem is, in my dev/localhost; I would get the results correctly if the token is correct, but when the token is bad or expired, I get a CORs error. How do I set this up so I can handle the results correctly?
Access to XMLHttpRequest at 'https://xcz3vfg4n7.execute-api.us-west-2.amazonaws.com/prod' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
xhr.js:210 POST https://xcz3vfg4n7.execute-api.us-west-2.amazonaws.com/prod net::ERR_FAILED 403
We ran into this same issue and since it was a painful to resolve, thought I would type up the solution.
Specifically we were receiving the CORs error via Axios in our React app, but not getting the error through cURL or Thunderclient (Postman-like extension for VS Code).
The resolution was actually missing headers on the "response" object from API Gateway.
Since cURL and Thunderclient/Postman don't care about CORs (because they server-based, not browser-based), those tools don't look for the 'Access-Control-Allow-Origin' header in the response.
We got back our preflight Options call 200 just fine, and then realized that the POST call was returning the 401 without an 'Access-Control-Allow-Origin' header.
Since the Authorizer is on the Method Request, it never goes past the Lambda proxy in the API Gateway and thus doesn't return full response headers.
So... the solution was actually really simple.
Go into "Gateway Responses"
Choose the "Unauthorized" option
Add the response headers (see screenshot)
IMPORTANT: Don't forget to "Redeploy" your API or the changes won't take effect
Example:
I want to fetch a information from steam web api's 'GetFriendsList' endpoint.When I am using fetch to do this from my front end javascript file.Im getting an error.
Access to fetch at 'https://api.steampowered.com/ISteamUser/GetFriendList/v1/?key=<apikey>&steamid=76561198364464404' from origin 'http://localhost:3001' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
I went to mdn and saw I must use
Access-Control-Allow-Origin: http://localhost:3000
Vary: Origin
in the fetch option.I did add these and no difference same error,I also added
mode: 'no-cors'
It worked this time but no response was returned from the steam web api.
I am really new to this.This is the first time using fetch.Any help regarding this is appriciated.THANK YOU.
When I attempt to request a lambda-backed API (using API gateway, deployed using the CLI and Cloud Development Kit) from my react app, I get the following error:
Access to XMLHttpRequest at 'https://xxxxxxxxxx.execute-api.eu-west-1.amazonaws.com/prod/xxxxx' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
GET https://xxxxxxxxxx.execute-api.eu-west-1.amazonaws.com/prod/xxxxx net::ERR_FAILED
My API resources defined using the CDK are all passed into this method
Like explain here, you need to enable CORS in API Gateway, BUT you also need to return an Access-Control-Allow-Origin header from your Lambda because API Gateway doesn't add that automatically to the responses.
Here is a sample of what my Lambda return for a simple Get :
return {
headers,
body: JSON.stringify(response.Item),
statusCode: 200
};
const headers = {
"Access-Control-Allow-Origin": "*", // Required for CORS support to work
"Access-Control-Allow-Credentials": true // Required for cookies, authorization headers with HTTPS
}
I’m trying to communicate a web page with a RestAPI server. When I try to do an http request the following message appears:
XMLHttpRequest cannot load https://(MyUrl). Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.
xhr.setRequestHeader("Access-Control-Allow-Origin", "*"); //Some line in my web page code
response.setRequestHeader("Access-Control-Allow-Origin", "*"); //Some line in my APIRest code
I have been doing some research about CORS and I don't understand which headers I have to include to the http request and what headers I have to include in the server to enable it. Should I add something in some .config?
For what I have understood, my petition is a “not-simple” request, as it’s a multipart request with an application/json part that also sends a token into the header. It’s a POST request.
Thanks!
It does not help that you set the headers in the client side. The server needs to have that header present in order to allow requests from third parties.
And so this will not work for you as long as the server does not have the Access-Control-Allow-Origin header set to allow your requests.

I'm trying to learn paypal payment. I have done a simple AngularJS application that use Paypal-Express-Checkout. As it says on the documentation, first of all I have to do the call SetExpressCheckout.
$http.post("https://api-3t.sandbox.paypal.com/nvp", request)
.success(function(data){
console.log(data);
}).error(function(error){
console.log(error);
});
In the object request there are all payment details.
But when I run the script, the result of http call is: XMLHttpRequest cannot load https://api-3t.sandbox.paypal.com/nvp. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access.
I tried to search this error, but I find nothing. How can I solve?
UPDATE: If the request comes from a form does not give me any error but if it come from http.post function it give me an error
You have to perform your Paypal transaction on the back end, and the message you're seeing is Paypal enforcing that notion. See this article on CORS for more info.
Your angular http call should be sending the basic transaction info to your server, which will then construct an API request for Paypal, handle the response from Paypal, and then convey that information for consumption by the client side.
