And `$current_link`, which may or may not be the same. It is used in the confirm and unsubscribe links, and depends on your webserver configuration. `example.com/subdir` here means your unsubscribe links will start `https://example.com/subdir/unsubscribe.php`.

$current_link = "certificatemonitor.org";

If you use Slack/Rocketchat, you can set up automatic posts whenever a subscription is added or removed, or checked and found to be expiring soon, expired or failed. To do this, create an [incoming webhook](https://api.slack.com/incoming-webhooks) and add its URL to the configuration (if you don't want this function, leave the string empty):

$slack_webhook = "https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX";

or

$slack_webhook = "https://my.rocketchat.com/XXXXXXXXXXXXXXXXXXXXXXXX";
