We are also having the same issue. Our meeting setting is the following:
registration is required
user must login to zoom to join meeting.
Now with these 2 conditions we expect to get the same ID form list Meeting Registrants API. Right?
If I see the ID when participant register and in the List Meeting Registrant API. It is the same.
But when I check the participant ID in the webhook. It is wrong. All other information is correct like host information, host id, participant name. Only the ID is wrong.
Please solve this ASAP. We’ve so many meetings integrated to our system and this thing causing trouble.
