PublishEventAction

PublishEventAction

Purpose Publish a domain event to a topic/queue (e.g., Kafka). Use for decoupled orchestration beyond the built-in API events.

M2M Token Support When publishing events via PublishEventAction, an M2M (Machine-to-Machine) token is automatically generated and included in the Kafka message payload. The token includes a hash of the message payload to prevent token reuse and expires after 15 minutes. This enables secure inter-service communication when consuming events in other services.

When to use it

• After main op (afterMainCreate/Update/DeleteOperation)
• After afterApiEvent for custom streams

Key fields

Example

{
  "id": "a270-publish-campaign",
  "name": "emitCampaignCreated",
  "topic": "marketing.campaign.created",
  "message": "{ id: this.campaign.id, createdBy: this.session.userId }"
}

Note: If ApiOptions.raiseApiEvent=true, Mindbricks already emits the standard API event; use PublishEventAction for additional custom events.
