Hi Team,
Is it possible to forward an invite to new recipients using Update event -

  1. 0&tabs=http#http-request

I test the update event api with the below scenario.[@](/users/na/?userId=1b30e9e4-0000-0003-0000-000000000000).com/calendar/events/id


  1. Sent invite to me only first.
  2. Called the Update api with below request(Trying to add you in the invite)
    It basically updates mine with XXX name. I get cancel meeting .
    Which means update api is replacing the attendees , not adding.
    Is that the case for Update api?

"subject" : "Test update calendar",
"attendees": [
"emailAddress": {
"address": "XXX@paypal .com"
"type": "Required"

    You can use event:forward() API call which allows the organizer or attendee of a meeting event to forward the meeting request to a new recipient.

    For example,

    POST /me/events/{id}/forward
