I have a feature request:  I loved the idea at first glance but then I was appalled to discover that there&#x27;s nowhere to register a callback URL for any of these events.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Webhook" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Webhook</a><p>To me it just seems obvious that there should be an either&#x2F;or option for SMS or HTTP especially since a metric shitton of people are already using slack and hipchat.<p>The transmission costs for HTTP are way more cheap than SMS so it seems like it would be in you guy&#x27;s interest to support webhooks in order to reduce outbound SMS costs.<p>TLDR; HTTP is the new SMS
