Hi -

I have been trying for over a week now to get oauth working between salesforce and my application.  I have experience getting oauth to work with Twitter and Youtube, so I figured this would be easy... 

BTW, I have set up Remote Access in my salesforce setup.  

I'm having problems on the very first step of the oauth process. This is what I am sending to get the RequestToken (I added the returns for clarity after the &'s)

https://login.salesforce.com/_nc_external/system/security/oauth/RequestTokenHandler?oauth_consumer_key=<My key>&
oauth_nonce=8114382&
oauth_signature_method=HMAC-SHA1&
oauth_timestamp=1266716665&
oauth_version=1.0&
oauth_callback=https%3A%2F%2Fwww.catchthecloud.com%2FSalesforceOAuth.aspx&
oauth_signature=fH85OWR29G3IXSp1sc3uf4WMD7w%3D

This seems to be correct as per: https://ap1.salesforce.com/help/doc/user_ed.jsp?loc=help&section=help&hash=access_data&target=remoteaccess_authenticate.htm

However, I'm getting a 400 - bad request error when sending it.  I'm also having problems sending it via POST, or if I put it in an Authorization header...

The C# code that I am using to generate this string is as follows:

Uri uri = new Uri("https://login.salesforce.com/");
string nonce = this.GenerateNonce();
string timeStamp = this.GenerateTimeStamp();

//Generate Signature
string sig = this.GenerateSignature(uri,
this.ConsumerKey,
this.ConsumerSecret,
this.Token,
this.TokenSecret,
method.ToString(),
timeStamp,
nonce,
out outUrl,
out querystring);

querystring += "&" + this.UrlEncode("oauth_callback") + "=" + this.UrlEncode("https://www.catchthecloud.com/SalesforceOAuth.aspx");
querystring += "&" + this.UrlEncode("oauth_signature") + "=" + this.UrlEncode(sig);

NameValueCollection oauthtokendata = null;
HttpWebRequest request = System.Net.WebRequest.Create(url+"?"+querystring) as HttpWebRequest;
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
using (TextReader reader = new StreamReader(response.GetResponseStream()))
{
oauthtokendata = HttpUtility.ParseQueryString(reader.ReadToEnd());
}
}

Towards the bottom of this code, I do a call to request.GetResponse(), and that's where it dies.  If I take the string that's been created and stick it in the address bar of a browser, I get the following response:

 1702Failed: Missing Consumer Key Parameter

Uri uri = new Uri("https://login.salesforce.com/");

 I have used several variations of Uri's in attempts to make this work, including https://login.salesforce.com/_nc_external/system/security/oauth/RequestTokenHandler, but nothing seems to work.

So -- hopefully someone can give me a tip to get this thing to work... I feel like I'm pretty close!

Thanks,

Beth
