Hi @mmimeault ,
I understand the inconvenience, but we do not have a supported API endpoint where you can see all meetings that you are both a host of and invited to as an invitee. I am not sure which 3rd party calendar services API you’re referring to and cannot make an official recommendation here.
Here’s something another developer proposed:
But note, this would only work best for meetings that have ended as opposed to scheduled meetings since the participant list is only finalized after a meeting concludes. You could technically also look to registrants, but it would work best if all meetings required registration and note that registrant ids change from meeting to meeting.
