Agora Cloud Recording records and saves voice calls, video calls, and interactive streaming. Send HTTPS requests from your business server to Agora to manage recording tasks on the server side.

To monitor recording status, enable the message notification service and receive Cloud Recording events through a webhook. Because Agora dynamically adjusts message notification server IP addresses, regularly query the IP addresses and update your firewall whitelist.
