I am trying to get calendar info from google in javascript. I ve read 'how to' manuals. They didn't help. Even this 'helpful' copypasted code (to authorize) didn't. Would somebody be so kind to teach me how to use google api? Maybe someone has some samples to share
And this beautiful js code :
<html>
<button id="authorize-button" onclick='handleAuthClick()'>Authorize</button>
<script type="text/javascript">
var clientId = '***';
var apiKey = '***';
var scopes = 'https://www.googleapis.com/auth/plus.me';
function handleClientLoad() {
gapi.client.setApiKey(apiKey);
window.setTimeout(checkAuth,1);
}
function checkAuth() {
gapi.auth.authorize({client_id: clientId, scope: scopes, immediate: true}, handleAuthResult);
}
function handleAuthResult(authResult) {
var authorizeButton = document.getElementById('authorize-button');
if (authResult && !authResult.error) {
authorizeButton.style.visibility = 'hidden';
makeApiCall();
} else {
authorizeButton.style.visibility = '';
authorizeButton.onclick = handleAuthClick;
}
}
function handleAuthClick(event) {
// Step 3: get authorization to use private data
gapi.auth.authorize({client_id: clientId, scope: scopes, immediate: false}, handleAuthResult);
return false;
}
// Load the API and make an API call. Display the results on the screen.
function makeApiCall() {
// Step 4: Load the Google+ API
gapi.client.load('plus', 'v1', function() {
// Step 5: Assemble the API request
var request = gapi.client.plus.people.get({
'userId': 'me'
});
// Step 6: Execute the API request
request.execute(function(resp) {
var heading = document.createElement('h4');
var image = document.createElement('img');
image.src = resp.image.url;
heading.appendChild(image);
heading.appendChild(document.createTextNode(resp.displayName));
document.getElementById('content').appendChild(heading);
});
});
}
</script>
Error Message (from Console):
'Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('file://') does not match the recipient window's origin ('null').'
so im stuck on 'gapi.auth.authorize'. nothing works after

You get the equivalent of 200$ per month for free. The price of each request is stated here: https://cloud.google.com/maps-platform/pricing/. Once you have used 200$ worth of requests, you will have to start paying.
The Google API Client Library for JavaScript is designed for JavaScript client-application developers. It offers simple, flexible access to many Google APIs. Note: This repo does not contain the source code for the gapi client.
Like many other Google web applications, Google Maps uses JavaScript extensively.
An API key is usually a unique string of letters and numbers. In order to start working with most APIs, you must identify yourself (register) and get an API key. You will need to add an API key to each request so that the API can recognize you.
Based on the error you're receiving, my guess is that you either do not have your Javascript Origin configured properly on the Google API console you got your Client ID from, and/or you are trying to run your script from the file system instead of through a web server, even one running on localhost. The Google API client, near as I've been able to tell, does not accept authorization requests from the file system or any domain that has not been configured to request authorization under the supplied Client ID.
