Zend google Calendar access not working anymore

Question

I have used the Zend framework to access a google calendar for about 1 year. Today, all of a sudden the Zend command getCalendarEventFeed() throws an error:

HTTP/1.1 403 Forbidden 
Content-type: text/html; 
charset=UTF-8 
Date: Mon, 17 Nov 2014 20:43:36 GMT 
Expires: Mon, 17 Nov 2014 20:43:36 GMT 
Cache-control: private, max-age=0 
X-content-type-options: nosniff 
X-frame-options: SAMEORIGIN 
X-xss-protection: 1; 
mode=block Server: GSE 
Alternate-protocol: 443:quic,p=0.01 
Connection: close

Yesterday everything still worked, I did not change anything at all.

I use Zend framework 1.11.12, today I also tried the latest version 1.12.9, same problem.

Any ideas?

Ditto here. Public calendar feed, so no authentication required, but suddenly nothing but 403.

Looks like Google deprecated the v2 calendar API today. See here: http://googleappsupdates.blogspot.com/2014/06/calendar-gdata-api-google-calendar.html
