# Use channel callback

Available in Classic and VPC

VOD Station provides a callback feature to check the channel status. When using callback, VOD Station automatically sends a callback message to the set `notificationUrl` whenever a channel status change event occurs. When requesting the following APIs, set the callback by entering the callback URL in `notificationUrl`.
