Question Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I'm trying to add external payment method integration to my React app. I'm sending a fetch request to the external payment method's API application, but I'm getting the following error.

This is my fetch code.

 async getPaymentsAccessToken() {
    const msg = await request<PaymentsAccessTokenResponse>(`https://apitest.crossdomain.com/accesstoken/get`, {
      method: 'POST',
      prefix: undefined,
      mode: 'cors',
      credentials: 'include',
      headers: {
        'Content-Type': 'application/json',
        client_id: this.client.client_id,
        client_secret: this.client.client_secret,
        'Ocp-Apim-Subscription-Key': this.client['Payments-Subscription-Key'],
      },
    });
    return msg;
  }

I got this error

Access to fetch at 'https://apitest.crossdomain.com/accesstoken/get' from origin 'mydomain.com' 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.

None of the settings I made on Plesk Apache and Nginx work.

Hi,

This is not necessarily a Plesk issue. You better post this on StackOverflow, where the React community can help you:

But I got this error, Shouldn't this error have something to do with plesk?

Access to fetch at 'https://apitest.crossdomain.com/accesstoken/get' from origin 'mydomain.com' 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.

The React community says the problem is with the plesk server.

Asking for help here every day isn't helpful. The lack of response on this topic is likely because of the fact this a specific issue to your setup which makes it hard for someone in the community to help you.

You'll have to do the trouble shouting yourself to find a solution to your problem. If you feel it's any issue with Plesk I suggest you contact Plesk support.
