Google Calendar API (v3) - PHP can write but not read? - php

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
}
}
?>
