Hi @r.asgari.g ,
I’m glad you are migrating! Have you checked out our migration guide for Web?
With Zoom and the Video SDK, sessions are created when the first user joins the session. Unfortunately, there is not a way currently to create a session via REST API, however, Zoom handles it automatically for you. We do have REST APIs for other session related use cases that I suggest you learn about here. Is there a reason you must start the session via REST API?
You can access cloud recording both via REST API and Webhook. I’d recommend using the cloud_recording_completed webhook to automatically perform whatever you are looking to do when the session has ended and the recording is ready.
Best,
Will
