ColdFusion and SmartSheet API

I'm attempting to call the smartsheet.com api and read the JSON data from a list sheet request. Im new to API's so I'm certain I'm missing much with my code.

Here is what I have so far:

<cfscript>

    apiURL = "https://api.smartsheet.com/2.0/sheets";

    apiToken = "xxxxxxxxxxxxxxxxxxxxxxxxx";

</cfscript>

<cfhttp url="#apiURL#" method="GET"  result="httpResp" timeout="120" charset="utf-8">

    <cfhttpparam type="header" name="Authorization" value="Bearer #apiToken#" />

</cfhttp>

However I do not receive the desired response:

I was attempting to use the sample provided to retrieve the data:

SmartSheet API 2.0 Example Request:

curl https://api.smartsheet.com/2.0/sheets -H "Authorization: Bearer ACCESS_TOKEN"

Example Response:

{ 

   "pageNumber":1,

   "pageSize":100,

   "totalPages":1,

   "totalCount":2,

   "data":[ 

      { 

         "accessLevel":"OWNER",

         "id":4583173393803140,

         "name":"sheet 1",

         "createdAt":"2015-06-05T20:05:29Z",

         "modifiedAt":"2015-06-05T20:05:43Z"

      },

      { 

         "accessLevel":"OWNER",

         "id":2331373580117892,

         "name":"sheet 2",

         "createdAt":"2015-06-05T20:05:29Z",

         "modifiedAt":"2015-06-05T20:05:43Z"

      }

   ]

}
