I would like my app to put an invitation for an event automatically in the user’s calendar. For example: I got an email for a flight and I only opened it, now I have the invitation in my calendar with “Accept” or “Deny”. How can I have this cool feature in my app? Thank you.
As a side note - you can’t access users’ calendars directly unless you know their calendar address; the feature you’ve described is managed by mail clients (like Gmail which recognizes an .ics attachment and puts it to your calendar).
Also as I remember that @James_App_Maker was doing something with Calendar invites.
