Retrieving Posted Data in a URL

Question

I am trying to retrieve data that a third-party vendor is posting to a URL that I supply. I think that I need to use "utl_http.request_pieces(url)" to retrieve the data, but I get "SIGNATURE (parameter names) MISMATCH VARIABLES IN FORM NOT IN PROCEDURE: NON-DEFAULT VARIABLES IN PROCEDURE NOT IN FORM:.." when I printout the contents of the table. Is this error from my retrieval of the url contents or from the third-party vendor's post to the url? Am I doing something wrong? Is this the correct procedure to use to retrieve posted data from a URL that is not passed as parameters?
Any help would be appreciated.
Thank you.

The reason I used deep linking was that was the only way that I could access the variables that were being sent from the first file. It took me most of the day finding a solution that would work! Is there a better way to capture the variables when I link to a file?
Here's what works for me in the file I've connetced to (the critical line is:  userName=o.connectionPw;):
import mx.managers.BrowserManager;
import mx.managers.IBrowserManager;
import mx.utils.URLUtil;
private var bm:IBrowserManager;      
public function init():void{
    bm = BrowserManager.getInstance();               
    bm.init("");
// The following code will parse a URL that passes string parameters after the "#" sign; for example:
    var o:Object = URLUtil.stringToObject(bm.fragment);               
    userName=o.connectionPw;
