Update Events

The backend service publishes update events to Google Cloud Pub/Sub whenever an application or channel changes state. Downstream services subscribe to the topic and use the eventType message attribute to filter for relevant events.

Topic

All update events are published to a single Pub/Sub topic: sdk-management.updates.

Each message includes an eventType attribute that identifies the kind of update:

ApplicationUpdateEvent

channel-update
