The hooks API is truly amazing. At this point I am trying to build a tracing/data lineage capability using the hooks API. Unfortunately, I cant seem to find how the hook will work with nodes like HTTP In.  
The xxxReceive hooks dont seem to be working on it.

Hi @mannharleen

The `onReceived` hook is triggered as part of the routing of messages between nodes.

In the case of the HTTP In node, it doesn't receive messages from an 'up stream' node - it generates messages in response to an HTTP request arriving. So you won't get the `onReceive` hook triggered for that.

I understand. So, it should work with the `onSend` hook then
