import { useEffect } from 'react';

useEffect(() => {
  let referral_url = new URL(window?.location?.href);

  if (
    referral_url?.searchParams?.has('gclid') &&
    referral_url?.searchParams?.has('via')
  ) {
    setTimeout(function () {
      document.cookie =
        'rewardful.referral=; expires=Thu, 01 Jan 1970 00:00:00 UTC; path=/; domain=' +
        window.location.hostname;
      console.log(
        'Deleted referral cookie as visit came from Google Ads (forbidden by Terms of Service)',
      );
    }, 2000);
  }
}, []);

Here is the vanilla javascript approach.

<script>
  document.addEventListener("DOMContentLoaded", function() {
    // Create a new URL object based on the current window location
    let referral_url = new URL(window.location.href);

    // Check if the URL contains 'gclid' and 'via' parameters
    if (referral_url.searchParams.has('gclid') && referral_url.searchParams.has('via')) {
      // Set a timeout function to delete a specific cookie after 2 seconds
      setTimeout(function() {
        // Set the cookie to expire in the past, effectively deleting it
        document.cookie = 'rewardful.referral=; expires=Thu, 01 Jan 1970 00:00:00 UTC; path=/; domain=' + window.location.hostname;
        // Log a message to the console
        console.log('Deleted referral cookie as visit came from Google Ads (forbidden by Terms of Service)');
      }, 2000);
    }
  });
</script>

Thanks @brettbatie lgtm!
