To properly implement cross-domain tracking in Mixpanel, you should consider the following key points: 1. Use cookie persistence: By default, Mixpanel uses cookies for cross-subdomain tracking. Ensure you're not using localStorage persistence, as this doesn't support cross-domain tracking.2. Keep cross_subdomain_cookie enabled: The default setting allows Mixpanel cookies to work across subdomains. Only disable this if you're dealing with hosted subdomains that don't allow cross-subdomain cookies.3. Use HTTPS: To ensure secure transmission of cookie data, it's recommended to use HTTPS for your requests.Here's how you can configure these settings: LBKS// create an instance of the Mixpanel object mixpanel.init('YOUR_PROJECT_TOKEN', { 'cross_subdomain_cookie': true, // Enable cross-subdomain tracking (default) 'secure_cookie': true // Prevent transmitting cookie with non-HTTPS requests });LBKSIt's important to note that if you're using hosted subdomains (like yourdomain.hostapp.com) that don't allow cross-subdomain cookies, you might need to disable cross-subdomain cookies or use a CNAME to change from yourdomain.hostapp.com to yourdomain.com.For more detailed information on Mixpanel cookie configuration, you can refer to the Mixpanel Cookie documentation.Remember to test your implementation thoroughly in a development environment before pushing to production. This will help ensure that your cross-domain tracking is working as expected.
