This doesn&#x27;t strike me as a developer tool (though it could obviously be used by developers).  It&#x27;s for consumers. I don&#x27;t know of many consumers who want to receive notifications via webhook.<p>If they did do webhooks then you could write one that sent out SMSs though - leave them to do the hard part while cutting them out of the loop!<p>Also I think it&#x27;s push notifications, not SMS.
