Had a good hunt around for an answer to this google apps query but can't find a direct answer so going to flick this one out to the community.
The plan: We have a Google Apps domain account and we want to make use of the calendar API and create a PHP web app that pushes events to the calendars of all users of a google apps domain when triggered.
Question: Is it possible to push to all users? Or from what I read is this impossible to achieve this without the users actually being logged in etc and authorizing itself?
I dont believe this is possible, wanted to try and set up a 'push to all' feature a while back, but no luck.
The best consolation is maybe creating one shared user/calendar and then sharing that out across all of the accounts. So a new user, with calendar title 'ExampleEventsForGroup' would then be shared back to Tom, Dick & Mary, and they could also add/modify events onto that calendar, thus pushing back out to all members.
Its a workaround, but for us, it works!
