I created a live event "Test LiveEvent" on Teams Calendar manually, and there are attendees in attendee engagement report.

austin_lee : I am able to get list of attendees here's what I did.

1. https://graph.microsoft.com/v1.0/me/events : [Post] sent request to this API to create an Event.

{"subject":"Let's go for lunch","body":{"contentType":"HTML","content":"Does noon work for you?"},"start":{"dateTime":"2017-04-15T12:00:00","timeZone":"Pacific Standard Time"},"end":{"dateTime":"2017-04-15T14:00:00","timeZone":"Pacific Standard Time"},"location":{"displayName":"Harry's Bar"},"attendees":[{"emailAddress":{"address":"first email address","name":"firstName"},"type":"required"},{"emailAddress":{"address":"{secound email address}","name":"{secound name}"},"type":"required"}],"allowNewTimeProposals":true,"transactionId":"7E163156-7762-4BEB-A1C6-729EA81755B8"}

Once, event is created I then used ListEvents API [Get] request to list my event which also returned attendees to the event.

Please follow above steps you will get attendees joining that event.

Thanks,

Manish Chitre

  I tried Calendar Event APIs already, I could get attendees from API if I give attendees on event created.
  But my scenario is to create a live event without attendees on calendar then send join url to attendees, and I could get the list of attendee who attended from calendar.
  I would like to know if there is any API to get the attendee report.
  Thanks.
  
  Best regards,
  Austin
