Why does the Google API not work in my Universal Windows App?


Error: 0x800a138f - JavaScript runtime error: Unable to get property 'setApiKey' of undefined or null reference

Hello I'm desperatly trying to get this to work on my Universal Windows App. There is a sample for Googles URL shortener with instructions on how to use the API.


All of this works when I run this in my Browser, but as soon as I start running this in my Universal Windows App, it won't work. I figured that it had something to do with the security of the UWP, inline skripts arent allowed and you can't load scripts from the web normally. You have to use a webview to load scripts from the web so I did this with this webview:

<x-ms-webview id="UrlShortenerWebview"src="ms-appx-web:///Pages/URLShortener/URLShortener.html" style="width: 200px; height: 200px; border: 1px solid black;"></x-ms-webview>

This is my URL Shortener html file:

	<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

	<script src="https://apis.google.com/js/api.js" type="text/javascript"></script>
		function appendResults(text) {
			var results = document.getElementById('results');

		function makeRequest() {
			var request = gapi.client.urlshortener.url.get({
				'shortUrl': 'http://goo,gl/fbsS'
			request.then(function (response) {
			}, function (reason) {
				console.log('Error: ' + reason.result.error.message);
		function init() {
			gapi.client.load('urlshortener', 'v1').then(makeRequest)
		gapi.load("client", init);
	<div id="results"></div>

Error: 0x800a138f - JavaScript runtime error: Unable to get property 'setApiKey' of undefined or null reference

I have no idea why that happens or what else I can do to fix this. Is it even possible to use the google api in windows apps???

Please check Rob's comments in your MSDN case: https://social.msdn.microsoft.com/Forums/windowsapps/en-US/bd101515-212b-4366-b60d-2807b2783f62

Rob mentioned two choices: calling local js files if Google permits it, or taking full control and stream your content to your x-ms-webview with navigateToLocalStreamUri method.
