The response to GET /{database}/api/calendar/events includes both events and notices. An event is an entry that is already booked on the calendar (an appointment, a meeting, a reminder, etc.). A notice is a separate document -- for example an invitation or a reschedule -- describing something about a meeting. Technically, a notice is not booked on the calendar.
Here's an example of a notice in JSON format:
{
"href": "/mail/dlawson.nsf/api/calendar/events/5BB9F2BCE41C33E185257E4200672A32-Lotus_Notes_Generated",
"id": "5BB9F2BCE41C33E185257E4200672A32-Lotus_Notes_Generated",
"summary": "Invitation: Quick update",
"location": "My office",
"start": {
"date": "2015-05-15",
"time": "17:00:00",
"utc": true
},
"end": {
"date": "2015-05-15",
"time": "18:00:00",
"utc": true
},
"class": "public",
"transparency": "transparent",
"sequence": 0,
"x-lotus-organizer": {
"data": "CN=Dean Melnyk/O=Peaks"
},
"x-lotus-summarydataonly": {
"data": "TRUE"
},
"x-lotus-noticetype": {
"data": "I"
},
"x-lotus-appttype": {
"data": "3"
},
"x-lotus-unid": {
"data": "5BB9F2BCE41C33E185257E4200672A32"
}
}
The x-lotus-notice property indicates it is a notice -- in this case an invitation.
It's subtle, but I think the calendar API is returning 404 because you are attempting to read a notice with an event URL. As you have discovered, you can't read the event until you have accepted the invitation.
