Show HN: Templated Webhooks

I'm building WebGun. It's SendGrid for Webhooks. A key part of our service is support of a new approach to webhooks we have developed that is essentially "template-driven transformations for web hooks". The purpose of them is to enable your app's end-users to customise your webhooks via templates, and integrate them with other services in new and unexpected ways. More detail here: http://webgun.io/articles/templated-webhooks We're pretty excited about the potential of templated webhooks, and the feedback so far has been very positive. Very keen to get feedback from the HN community.
