List webinar participants api shows participant email address in name field

Hi

List Webinar Participants api endpoint [ GET - /past_webinars/{webinarId}/participants ] response show participants email address in the name field instead of showing full name (first_name + last_name)

I aslo checked the List webinar registrants response has the first name and last name for all webinar registrant [GET /webinars/{webinarId}/registrants ]

When webinar attendee report is downloaded from zoom.us >> reports section it has attendee first name and last name

Below is the screen shot

Please let me know how this issue can be resolved.

Hi @djoshi can you please call it again and send the zm-tracking-id from the response headers?

Below is the tracking info from response header
