contactsService = new google.gdata.contacts.ContactsService('GoogleInc-jsguide-1.0');
}

var token = google.accounts.user.login(scope);
}

function logMeOut() {

if (google.accounts.user.checkLogin(scope)) {
google.accounts.user.logout();
}

function getMyContacts() {
var contactsFeedUri = 'https://www.google.com/m8/feeds/contacts/ziaur18@gmail.com/full';
var query = new google.gdata.contacts.ContactQuery(contactsFeedUri);

// Set the maximum of the result set to be 5
query.setMaxResults(500);

contactsService.getContactFeed(query, handleContactsFeed, handleError);
}

var handleContactsFeed = function(result) {



var entries = result.feed.entry;

var t = "Contacts List <table border = 1 align = center width = 50%>";
t = t + "<tr><td align = center>Name</td><td>Email Address</td></tr>"; //row1

for (var i = 0; i < entries.length; i++) {
var contactEntry = entries[i];
var emailAddresses = contactEntry.getEmailAddresses();
var name=contactEntry.getTitle().getText();

for (var j = 0; j < emailAddresses.length; j++) {
var emailAddress = emailAddresses[j].getAddress();
t = t + "<tr><td align = center>"+name+"</td><td>"+emailAddress+"</td></tr>";
}
}

t = t + "<table>";

document.getElementById("showhide").innerHTML = t;
}

function handleError(e) {
alert("There was an error!");
alert(e.cause ? e.cause.statusText : e.message);
}


</script>

Hi,

I briefly checked Contacts API documentation and it states that OAuth 2.0, is used for authentication.
Unfortunately OAuth 2.0 is not supported in series 40 web apps and for OAuth 1.0 you would have to use a proxy to handle authentication flow.
