Hello everyone,

I'm currently consuming APIs hosted on an external server using Java( or any other server side language), and everything works smoothly. However, when attempting to consume the same APIs in JavaScript, I encounter the 'Access-Control-Allow-Origin' error.

After some research, I discovered that browsers implement security checks leading to this issue. Can anyone advise on how to disable these security checks or resolve this issue when accessing the website in the Firefox browser? Any insights would be greatly appreciated. Thanks in advance!

Issue: Browsers implement security checks, such as verifying the CORS headers in the server response, to ensure the requested domain is allowed. If the server is on a different domain, the browser checks if the requesting domain is whitelisted in the CORS headers. For example, if you're sending a request from the domain 'https://fescobilling.pk/xyz' to a server hosted on 'https://pescobilling.pk/abc', the browser will verify that the xyz server has whitelisted the abc domain or IP.

Solution: To resolve this issue, you'll need to request the server's technical team to whitelist your domain. Alternatively, you can consume the APIs from a server-side language instead.
