Hi @ViaraiX!
Thank you for reaching out to the Zoom Developer Forum, I am happy to help here!
I have found similar post to yours and one of my colleges provided an answer to this issue.
I am linking here the post:
Which states that meetings created with type 2, and prescheduled=false will be normal scheduled meetings, and can be started as usual.
If prescheduled=true, this meeting can’t be started yet—it will need to be updated to a scheduled meeting before it can be started.
Hope this helps,
Elisa
