Tracking users across subdomains¶

If you want to track your visitors across multiple sub-domains, you can add a domain name parameter to $A1Config to make the user visible across sub-domains :

<script>
var $A1Config = {
    key: “yourKeyHere”,
    tenantId: 123,
    domain: “mydomain.com”
};
</script>

Note that using an invalid domain (such as the example above on any website other than *.mydomain.com) will result in the cookie silently failing to write, which will prevent us from tracking that user on that website.
