Insert event to Google Calendar using php

Question

I'm trying to perform a cURL request to google calendar api using their guide, that says:

POST https://www.googleapis.com/calendar/v3/calendars/{name_of_my_calendar}/events?sendNotifications=true&pp=1&key={YOUR_API_KEY} Content-Type: application/json Authorization: OAuth 1/SuypHO0rNsURWvMXQ559Mfm9Vbd4zWvVQ8UIR76nlJ0 X-JavaScript-User-Agent: Google APIs Explorer { "start": { "dateTime": "2012-06-03T10:00:00.000-07:00" }, "end": { "dateTime": "2012-06-03T10:20:00.000-07:00" }, "summary": "my_summary", "description": "my_description" }

How am I supposed to do that in php? I wonder what parameters I should send and what constants I should use. I'm currently doing:

 $url = "https://www.googleapis.com/calendar/v3/calendars/".urlencode('{name_of_my_calendar}')."/events?sendNotifications=true&pp=1&key={my_api_key}"; $post_data = array( "start" => array("dateTime" => "2012-06-01T10:00:00.000-07:00"), "end" => array("dateTime" => "2012-06-01T10:40:00.000-07:00"), "summary" => "my_summary", "description" => "my_description" ); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_POST, 1); // adding the post variables to the request curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data); $output = curl_exec($ch); curl_close($ch);

but the response is:

{ error: { errors: [ { domain: "global", reason: "required", message: "Login Required", locationType: "header", location: "Authorization" } ], code: 401, message: "Login Required" } }

How should I format my parameters?

Did you read developers.google.com/google-apps/calendar/auth? — Daan

Yes, my code works on an example where I just parse events from the same calendar. — Gustav

Hmm. Not sure, I've never worked with this API before. You may want to give the official PHP API package a try: code.google.com/p/google-api-php-client Hope this helps a bit! — Daan

I noticed this question is asked quite some time ago, however after figuring out the post-parameter problem after some time I thought it might be useful to others to answer it. First within '$post_data', I switched the 'start' and 'end':

$post_data = array( "end" => array("dateTime" => "2012-06-01T10:40:00.000-07:00"), "start" => array("dateTime" => "2012-06-01T10:00:00.000-07:00"), "summary" => "my_summary", "description" => "my_description" );

Secondly, I figured Google Calendar API expected the data to be json, so in curl_setopt:

curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($post_data));

This worked perfectly for me, hope it's useful to someone else as well!

For me is not working. i tryed that code, or i'm doing wrong key, but i don't think so. is the one under : "Key for server apps (with IP locking) " i allowed all IP for now. authorization required even for me. Can i have access to your complete example please?
