Grabbing email addresses from cloud recording chat transcript

Hello Zoom community,

I am currently in the process of migrating an integration where I was previously processing chat messages from a webinar realtime using the webhook event “chat.message_sent”. The end goal is to instead process all of the chat messages at once at the end of the webinar.

I thought I would have been able to do this by downloading the chat transcript from the cloud recordings at this endpoint “get/meetings/{meetingId}/recordings”, but the transcript provided is only giving me the full name of the users. I need the emails as well.

Is there a setting or workaround for parsing all of the chat messages with their full name, and email addresses at once? I’m assuming this is possible because the webhook payload was providing me with email addresses.

Thanks,
