BigCommerce webhooks listener in rails - ruby-on-rails

Question

I'm following the instructions here http://developer.bigcommerce.com/api/webhooks/quickstart to set up webhooks to initiate some third-party order processing. We've been doing this on an hourly batch, real-time webhook triggers will save us a lot of lag time.
I think I've set up the webhook broadcaster, but can't see any evidence that it's being fired- I've created a bunch of new orders and nothing reaches the rails server.
How can I tell if BigCommerce is firing events when / where I expect?
Generated the access token for the given app/user/domain:
curl -XPOST -d '{
"client_id":"[BigCommerceAppClientId]",
"client_secret":"[BigCommerceAppSecret]",
"user":"admin",
"token":"[adminAPIToken]",
"store_domain":"https://[myStore].mybigcommerce.com"
}' https://hooks-beta.bigcommerce.com/token
yields ===>
{
"access_token":"[webHooksAccessToken]",
"producer":"store/[myStoreKey]"
}
Subscribed to webhooks for store/events/listener:
curl -XPOST -d '{
"producer":"store/[myStoreKey]",
"scope":"store/order/created",
"deliverymethod":"HTTP_POST",
"destination":{"url":"http://[myPublicRailsServer]/hooks"}
}' -H 'X-Auth-Client: [BigCommerceAppClientId]' -H 'X-Auth-Token:[X-Auth-Token]' https://hooks-beta.bigcommerce.com
yields ===>
{
"client_id":"[webHooksAccessToken]",
"created_at":"2013-06-27T19:57:38+00:00",
"deliverymethod":"HTTP_POST","destination":{"url":"http://[myPublicRailsServer]/hooks"},
"id":651,
"producer":"store/[myStoreKey]",
"scope":"store/order/created",
"updated_at":"2013-06-27T19:57:38+00:00"
}

I lied. The problem was apparently trying to use https instead of http. Everything works as expected.
Furthermore- BigCommerce provides a hook to check the active clients for a given application:
curl -XGET -H
'X-Auth-Client: [BigCommerceAppClientId]' -H
'X-Auth-Token: [BigCommerceAppSecret]'
