Intelligent Media Services (IMS) supports callback event notifications in Simple Message Queue (SMQ, formerly MNS) queues. This topic describes the features of callback event notifications in IMS, along with the references for configuring them.
Callback event notification
Features
When you use features of IMS such as media asset upload, media processing, and online editing, you can configure callback events to obtain the task progress and status at the earliest opportunity. This way, you can perform other business operations based on the events.
When an event occurs, the IMS server calls back the event and writes it into the SMQ queues. Then, you can query the event by consuming messages in the queues.
References
You can set callback events through the IMS console or OpenAPI. For more information, see Configure callback events.
