Additional context
I have more than 100 hosts created like this one, using the API with login_type 99, but only this one is not able not join his meetings.
From the request body that you are sharing here, you are only passing the “topic”, that could be the reason why this host can not start the meeting.
A guess is not an answer. I would rather get an sincere “I don’t know”.
Here is the documentation for calling the Create meeting endpoint Create Meeting
Have you read the documentation? It points there is no need for any parameter when using this endpoint. All of them are optional.
So having one or ten parameters on the requests body makes no difference.
We deleted this bugged Zoom host user to fix this issue. You can close this topic or do whatever you want as usual.
