I'm trying to access a public calendar (from Google Calendar) that contains national holidays:

calendarId: 'pt_br.brazilian#[email protected]'

As the calendar is public, I thought I would be able to access it using only the API Key:

function OnLoadCallback() {

    var config = {

        client_id: '32j4lk32j5kj342l5h.googleuser.com', //fake client id

        scope: 'https://www.googleapis.com/auth/calendar.readonly'

    };

    gapi.client.setApiKey('fId345AM20HXXXXXXXXXXXXXXXXgT3f9kyp2REfkaw2'); //fake api key

    gapi.client.load('calendar', 'v3', function() {

        var today = new Date(),

            request;



        request = gapi.client.calendar.calendarList.get({

            calendarId: 'pt_br.brazilian#[email protected]',

            timeMin: (new Date(today.getFullYear(), today.getMonth(), today.getDay(), 0, 0, 0, 0)).toISOString(),

            timeMax: (new Date(today.getFullYear(), today.getMonth(), today.getDay(), 23, 59, 59, 999)).toISOString(),

            fields: 'items(creator(displayName,email),end,endTimeUnspecified,start,summary)'

        });



        request.execute(function(response) {

            window.alert('length of items: ' + response.items.length);

        });



    });

}

However, I keep getting the following response, which is a 401 (unauthorized) error:

{

 error: {

  errors: [

   {

    domain: global,

    reason: required,

    message: Login Required,

    locationType: header,

    location: Authorization

   }

  ],

  code: 401,

  message: Login Required

 }

}

Can someone clarify whether what I'm trying to do is achievable or not?

And finally if it is possible - what do I have to change referring to my current code?

I was able to do the same thing using jQuery.

var mykey = 'your_api_key'; // typically like Gtg-rtZdsreUr_fLfhgPfgff

var calendarid = 'you_calendar_id'; // will look somewhat like [email protected]



$.ajax({

    type: 'GET',

    url: encodeURI('https://www.googleapis.com/calendar/v3/calendars/' + calendarid+ '/events?key=' + mykey),

    dataType: 'json',

    success: function (response) {

        //do whatever you want with each

    },

    error: function (response) {

        //tell that an error has occurred

    }

});

However you need to be sure you have done the following:-

1) Register a project at https://code.google.com/apis/console

2) Generate a Simple API Access key

3) Ensure Calendar API is activated under services.
