I wanted to create busy event at a specific time range. And I created it using Google Calendar API Event Reference. In the document it says there is transparency parameter for this usage.
"opaque" - The event blocks time on the calendar. This is the default value.
I gave this value for transparency parameter. But then I was able to create another event at this time. But I want to lock this time when an event created as busy so noone can take event at this time no longer. Am I using wrong parameter? If I am which parameter I should use?
