How do I parse json array object with Angular.js?

I am consuming a Yammer RESTful API with AngularJS. I have been able to get the yammer user.json api to work but need guidance consuming and displaying the yammer messages.json api. If anybody could help with the scope syntax, that would be cool.

Parse json to return messages > body > rich Here is the code:

Controller

function YammerGetUserCtrl($scope, $http ) {  
 $http.get('https://api.yammer.com/api/v1/messages.json', {headers: {'Authorization': 'Bearer xxxxxxxxxxxxxxx'}}).  
      success(function(data) {  
       $scope.users = data;  
      console.log($scope.users)  
     });  
 }

JSON

    {
        "threaded_extended": {},
        "messages": [
            {
                "id": 654897910,
                "sender_id": 1506696042,
                "replied_to_id": null,
                "created_at": "2016/02/12 20:55:02 +0000",
                "network_id": 11319,
                "message_type": "update",
                "sender_type": "user",
                "url": "https://www.yammer.com/api/v1/messages/654897910",
                "web_url": "https://www.yammer.com/arrow.com/messages/654897910",
                "body": {
                    "urls": [
                        "https://www.youtube.com/watch?v=yueP7V6Wddc&index=7&list=PLKsggbHA8DermEtbMcC80M38cuR5rFdgi"
                    ],
                    "parsed": "Our shiny new aerospace [[tag:8909387]] that ran in Colorado markets during Super Bowl 50 is going viral!

            .....
    }

So I would like to display the url and rich excerpt from the body. How can I do it?
