@mdickens , @gianni.zoom , where you ever able to get the above resolved? I am also facing the issue of an empty “custom_questions”: array, whenever I try to use GET https://api.zoom.us/v2/webinars/<>/registrants.
Hi @markus.radons , I did not hear back from the other customer. As you can see from my last response, I was not able to reproduce what they were experiencing.
Can you share your process and settings?
