Hello,
I’m unsure if Elementor triggers any actions while creating an alert. However, assuming the action name is elementor_alert_created, here’s an example of how to send an SMS when this event occurs:
add_action('elementor_alert_created', function ($alert_content) {
$receivers = [
'+1111111111', '+1111111112', // ...
];
wp_sms_send($receivers, $alert_content);
});
