Email Settings APIs Authentication - email

Question

I would like to use the Email Settings API with Apps Script to manage all users signatures on a Google Site. I have used Documents Data APIs before with 2-legged OAuth and it worked just fine. I am currently stuck on the authentication step for Email Settings API.
Code example:
// Setup OAuthServiceConfig
var oAuthConfig = UrlFetchApp.addOAuthService("signature");
oAuthConfig.setAccessTokenUrl("https://www.google.com/accounts/OAuthGetAccessToken");
oAuthConfig.setRequestTokenUrl("https://www.google.com/accounts/OAuthGetRequestToken");
//I left scope empty to gain access to all APIs would this scope work scope=https://apps-apis.google.com/a/feeds/emailsettings/2.0/
oAuthConfig.setAuthorizationUrl("https://www.google.com/accounts/OAuthAuthorizeToken");
oAuthConfig.setConsumerKey("domain.com");
oAuthConfig.setConsumerSecret("consumerSecret");
// Setup optional parameters to point request at OAuthConfigService. The "signature"
// value matches the argument to "addOAuthService" above.
var options =
{
"method" : method,
"oAuthServiceName" : "signature",
"oAuthUseToken" : "always"
};
var result = UrlFetchApp.fetch("https://apps-apis.google.com/a/feeds/emailsettings/2.0/"+domainName+"/"+userName+"/signature", options);
Logger.log(result);
I get this error: "Unexpected Error (line 37)" which is
var result = UrlFetchApp.fetch("https://apps-apis.google.com/a/feeds/emailsettings/2.0/"+domainName+"/"+userName+"/signature", options);
Any thoughts on what I am doing wrong?

Hope this will help you. This is an working example which will get the user's HTML signature or Update HTML signature
/*
----------------------------------------------------------------------------------
This function will update the HTML signature of a user.
Input will be jason data
To disable signature, pass an empty string as signature value
sample parameter
ob = {user='hps', signature='<b>Regards</b><br>Waqar'}
To disable signature
ob = {user='hps', signature=''}
----------------------------------------------------------------------------------
*/
function updateSignature(ob) {
//ob = {};
//ob.user = "hps";
//ob.signature = "<b>Regards</b><br>Waqar";
var base = 'https://apps-apis.google.com/a/feeds/emailsettings/2.0/';
var xmlRaw = '<?xml version="1.0" encoding="utf-8"?>'+
'<atom:entry xmlns:atom="http://www.w3.org/2005/Atom" xmlns:apps="http://schemas.google.com/apps/2006">'+
'<apps:property name="signature" value="'+htmlEncode(ob.signature)+'" />'+
'</atom:entry>';
var fetchArgs = googleOAuth_('emailSetting',base);
fetchArgs.method = 'PUT';
fetchArgs.payload = xmlRaw;
fetchArgs.contentType = 'application/atom+xml';
var domain = UserManager.getDomain();
var url = base+domain+'/'+ob.user+'/signature';
var urlFetch = UrlFetchApp.fetch(url, fetchArgs);
var status = urlFetch.getResponseCode();
return status;
}
//-----------------------------------------------------------------------------------------------------------
//This function will retreive Signature settings as json.
/*Sample returned object
{user=hps, signature=<b>Regards</b><br>Waqar}
*/
//-----------------------------------------------------------------------------------------------------------
function retrieveSignature(user) {
var user = 'hps';
var base = 'https://apps-apis.google.com/a/feeds/emailsettings/2.0/';
var fetchArgs = googleOAuth_('emailSetting',base);
fetchArgs.method = 'GET';
var domain = UserManager.getDomain();
var url = base+domain+'/'+user+'/signature?alt=json';
var urlFetch = UrlFetchApp.fetch(url, fetchArgs);
var jsonString = urlFetch.getContentText();
var jsonArray = Utilities.jsonParse(jsonString).entry.apps$property;
var ob = {};
ob.user = user;
for(var i in jsonArray){
ob[jsonArray[i].name] = jsonArray[i].value;
}
return ob;
}
//Google oAuthConfig..
function googleOAuth_(name,scope) {
var oAuthConfig = UrlFetchApp.addOAuthService(name);
oAuthConfig.setRequestTokenUrl("https://www.google.com/accounts/OAuthGetRequestToken?scope="+scope);
oAuthConfig.setAuthorizationUrl("https://www.google.com/accounts/OAuthAuthorizeToken");
oAuthConfig.setAccessTokenUrl("https://www.google.com/accounts/OAuthGetAccessToken");
oAuthConfig.setConsumerKey("anonymous");
oAuthConfig.setConsumerSecret("anonymous");
return {oAuthServiceName:name, oAuthUseToken:"always"};
}
//This function will escape '<' and '>' characters from a HTML string
function htmlEncode(str){
str = str.replace(/</g,'<');
return str.replace(/>/g,'>')
}
