It would be amazing if it was possible to create calendar events from a link, like in Google Calendar.

For example: calendar.google.com/calendar/render?action=TEMPLATE allows one to then put in the text, dates, details, location etc.

This allows for easy event sharing with others, but also makes it possible to create events through an app (which simply puts together and returns a string with the link). This makes it easy to add custom behaviour with code, without needing to open up the full API to users - it could be a relatively simple stepping stone in lieu of Calendar API.

I apologise if something like this already exists, but to the best of my searching abilities, it does not currently seem to be possible.
