I’m using this endpoint “GET /report/meetings/{meetingId}/participants” to get meeting participant reports.

Is there a way to make your API return specific fields only (projection) to improve the response time? For example I want the “nextPageToken and user\_email of each participant” only.

@cyan1 we don’t have the ability to customize which fields get returned from our APIs. However, if you’re only interested in user emails, you may be able to use a lighter API to accomplish this. The reports and dashboard apis are among the heaviest / most computationally expensive endpoints we have. The [get past meeting participants](https://marketplace.zoom.us/docs/api-reference/zoom-api/methods/#operation/pastMeetingParticipants) API may be of value here.
