Wufoo and REST API

Wufoo ( is a great service for creating user forms and getting input. Build a form interactively, let people fill it out, and Wufoo collects the results. If you haven't checked it out before, I highly recommend this great service.

I was simply parsing the emails when they were sent upon form completion but that is a real hassle due to HTML. However, Wufoo has a really good REST API so I started playing around with it. Here, in C#, is how I used their API to get my data. This can easily be converted into SAS as well:

The HttpGet:

internal static string HttpGet(string uri, string apiKey)
var pairs = new StringBuilder();
var req = WebRequest.Create(uri) as HttpWebRequest;
req.Timeout = 300000;
req.Credentials = new NetworkCredential(apiKey, string.Empty);
req.UserAgent = "AlanC";
req.ContentType = "text/html";
req.Method = "GET";

// Get response

using (var response = req.GetResponse() as HttpWebResponse)
if (response != null)
WebResponse resp = req.GetResponse();
if (resp != null)
var sr = new StreamReader(resp.GetResponseStream());
return sr.ReadToEnd().Trim();
return null;
return null;

The call to the method:

XDocument xd = XDocument.Parse(HttpGet(@"", "XXXX-XXXX-XXXX-XXXX"));

The https://xxxxx would correspond to your domain on wufoo.
The xxxxx after forms in the uri would be the form id assigned by Wufoo.
The XXX-XXXX-etc. is the API Key assigned by Wufoo.

The above can be found on the Wufoo site. Just look at the Wufoo API information to find out how to obtain it.
