Is there any API to download the list of meeting members who joined with their name an email
My suggestion for this would be something already suggested to you in a related post you just made:
By design, Jitsi by default does not keep track of occupant details once the meeting is over. You can use the module mentioned in the thread above to post room/occupant events to your own API endpoint as it happens. You endpoint can collate that information and you can then use the data that as needed.
