When you use Intelligent Media Services (IMS) for media asset upload, media processing, or online editing, you need timely updates on task progress to trigger downstream operations. IMS delivers callback event notifications through Simple Message Queue (SMQ, formerly MNS) queues, so you can track task status and respond automatically without polling.
How event notifications work
When an IMS operation triggers a callback event, the IMS server writes the event to an SMQ queue. Your application consumes messages from the queue to retrieve event data and run downstream business logic.
IMS generates callback events for the following operations:
| Operation | Description |
|---|---|
| Media asset upload | Notifies when media assets are uploaded |
| Media processing | Notifies on media processing task progress and status |
| Online editing | Notifies on online editing task progress and status |
Configure callback events
Set up callback event notifications through the IMS console or OpenAPI. For step-by-step instructions, see Set callback events.
