Can't get almost all information from event from service Hook - visual-studio

Question

I am trying to use the Trello service hook with Team Foundation Server. I have followed this tutorial and the connection worked without problems but, I can't get the informations I need from the Event JSON:
The Description I Tried
This is the Event JSON:

This is the Request that was send to Trello:
Method: POST
URI: https://api.trello.com/1/cards?key=7d6630fd03ac2b6fc9fde2f2ef0c4096&token=********
HTTP Version: 1.1
Headers:
{
Content-Type: application/json; charset=utf-8
}
Content:
{
"name": "Test Nº ",
"desc": "Description: ",
"pos": "top",
"due": null,
"labels": "green",
"idList": "5935a0d45ff8e5a6c8f828b9"
}
The only field that I could get/read from the Event JSON was the "message".
What am I doing wrong?

Answer 1

If you want to get the push ID and comments, the description is:
{{push.pushId}}
{{push.commits[0].comment}}

Answer 2

Update
Eddie is right you should use push as the resource in this case. The docs are not so clear. In the end, it was something so simple. However the corresponding checkin is not work for Code checked in event.
The docs could definitely be more clear in how the resource are for each event which applied to help avoid this confusion.
The basic form of the placeholder is {{resource.field}} where
resource is the name of the resource raising the event (workitem, build, etc) and field is a field within the resource section of the
event, like id. So, if the subscription were for a completed build,
it might be something like:
Build {{build.id}} completed at {{build.finishTime}}
Seems the issue is you are using the wrong placeholder in this case. According to your send Request , resource.pushID & resource.commits.[0].comment is not replaced by values from the event that was raised.
