How do I determine branch name or id in webhook push event?

Question

I was ecstatic when I got a simple webhook event listener working with GitHub push events on my Azure site, but I realize now I'm not seeing the branch name or id in the json payload (example here https://developer.github.com/v3/activity/events/types/#pushevent)

I thought maybe "tree_id" would be it, but it doesn't seem to be. I couldn't find any info about this in GitHubs's doc. Maybe I need to take one of the id's from the event and make another api call to get the branch? The reason for this is I want to be able to link GitHub push events with my app portfolio, which has branches defined. So, the push events are a way to see code change activity on my different apps -- and knowing the branch is therefore important.

I wrote to GitHub support, and they told me that the branch name is part of the "ref" element in the root of the json payload. When parsing from a JToken object called jsonBody, the C# looks like this

var branchName = jsonBody["ref"].ToString().Split('/').Last();

For example in "refs/heads/master", the branch name is "master"
