Uncaught TypeError: Cannot read property 'getAuthToken' of undefined?

chrome.identity.getAuthToken({ 'interactive': true },
			function(token) {
				if (chrome.runtime.lastError) {
					alert(JSON.stringify(chrome.runtime.lastError));
					} else {
						alert(token);
					}
		});

Here, i am getting the error in first line.

and this the manifest of permission: "permissions": ["identity", "https://www.googleapis.com/", "https://accounts.google.com/", "https://*.googleusercontent.com/","https://*.chromiumapp.org/*", "https://accounts.google.com/o/oauth2/v2/auth"],

@jliukai

you have to do it from a background script otherwise it will not work and it will give you chrome identity as undefined.

https://github.com/GoogleChrome/chrome-app-samples/tree/master/samples/identity

here in the example in the manifest you have background script defined as main.js this script uses index.html to load the identity script and so it’s working as a backround script. Just check the background scripts docs and how to exchange events between content and background and you will be good.

It may require providing a “key” value in your manifest as well. You can either use the same key as the one you get when you upload your extension to the webstore or try packing an extension to generate a new one (though I couldn’t get this second approach working myself).

it may?
