Google Calendar API (v3) - PHP can write but not r

Question

I spent all day figuring out the Google Calendar API. I finally managed to insert an event in my Google Calendar but now I cannot seem to get the "list" command working.

The following code works:

    <?php
    $start = array(
        "dateTime" => $date . "T" . $start_time . ":00",
        "timeZone" => "Europe/Berlin"
    );

    $end = array(
        "dateTime" => $date . "T" . $end_time . ":00",
        "timeZone" => "Europe/Berlin"
    );

    $headerarray = array(
        'Content-type: application/json',
        'Authorization: Bearer ' . $access_token,
        'X-JavaScript-User-Agent: Google APIs Explorer'
    );

    $post_data = array(
        "start"       => $start,
        "end"         => $end,
        "summary"     => $title,
        "description" => $description,
        "key"         => $api_key
    );

    $post_data = json_encode($post_data);

    $url = 'https://www.googleapis.com/calendar/v3/calendars/' . $calendar_id . '/events';

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_HTTPGET, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headerarray);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    $response = curl_exec($ch);
    $response = json_decode($response);
    ?>

This piece of code creates a new event in my calendar, so I should have everything set up correctly, right?

However this code does not work:

    <?php
    $headerarray = array(
        "Authorization: Bearer " . $access_token,
        "X-JavaScript-User-Agent: Google APIs Explorer"
    );

    $url = 'https://www.googleapis.com/calendar/v3/calendars/' . $calendar_id . '/events?key=' . $api_key;

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headerarray);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    $response = curl_exec($ch);
    $response = json_decode($response);
    ?>

In this case I get the following response: Access Not Configured. Please use Google Developers Console to activate the API for your project.

But that is not the case. I configured the access correctly, or else I would not be able to insert events into the calendar, right? Maybe I am not using cURL right?

This is the reference for the list function: https://developers.google.com/google-apps/calendar/v3/reference/events/list

What am I not seeing here? Any help is highly appreciated.

Try this one :

• Go to : https://console.developers.google.com
• select project
• go to: APIs and auth
• Activate calendar api

I spent my whole day to create the event , I'm able to fetch the event

here is my code to fetch data from google oauth and I am using the codeigniter framework.

<?php
    // product_config
     $config['google_id'] = '';
     $config['google_secret'] = '';

    // oauth file
    function get_calendar_events(OAuth2_Token_Access $token){
        try{

            $max_results = 250;
            $url = 'https://www.googleapis.com/calendar/v3/calendars/primary/events?showDeleted=false&$orderBy=email&maxResults='.$max_results.'&alt=json&v=3.0&oauth_token='.$token->access_token;
            $google_events = json_decode(file_get_contents($url), true);

            return $google_events;

        }catch (Exception $e) {
            // Exception
        }
    }

    /*** Controller ***/
    function myCalendar() {
        try {
            $events = array();
            $provider_name = 'google';
            $provider = $this->oauth2->provider($provider_name, array(
                    'id' => $this->config->item($provider_name.'_id', 'product_config'),
                    'secret' => $this->config->item($provider_name.'_secret', 'product_config'),
                    'scopes' =>  array('https://www.googleapis.com/auth/calendar',
                                'https://www.googleapis.com/auth/calendar.readonly')
            ));

            if (!$this->input->get('code')){ // access authorizing
                // By sending no options it'll come back here
                $provider->authorize();
            }else{
                // Get the Token
                $token = $provider->access($this->input->get('code'));
                $events  = $provider->get_calendar_events($token);
        }catch (Exception $e) {
            // Exception
        }
    }
?>
