Event Dispatcher


This plugin informs external systems about changes in CELUM. Various filters allow you to restrict the scope of the events, so that only relevant events are dispatched. Both the filters and the dispatcher allow for custom implementations through the use of beans. By default we ship simple GET and POST implementations for use in Webhooks.

General properties


type: String, required: yes, default: -

The license key for the plugin (product: eventDispatcher), provided by brix.


type: bean names (comma separated), required: no, default: -

Event filters to apply - needs to pass all of them in order to be dispatched. Providing no filters will dispatch all events. Known implementations:

  • eventFilterByName
  • eventFilterByUser
  • eventFilterByNode
  • eventFilterByNodeType (since 1.7.1)
  • eventFilterByMetadataUpdated (since 1.9.1)
  • eventFilterBySearchExpression (since 1.12.0)

type: bean names (comma separated), required: yes, default: eventDispatcherSimpleGet

Event dispatchers to inform about the event, all will be called in order. Known implementations:

  • eventDispatcherSimpleGet
  • eventDispatcherSimplePost
  • eventDispatcherJsonPost (since 1.9, configure eventDispatcher.jsonTemplate, e.g. {"channel": "Plugins", "username": "EventBot", "text": "$eventType: [$name](https://mediahub.brix.ch/main/opennodeview.do?assetId=$id)"})
  • eventDispatcherJsonPostInfofields (since 1.9, configure eventDispatcher.infofields as a list of infofield-id:name, e.g. 123:brand,456:sku , eventDispatcher.nodeRefsAsArray as boolean if you want to get NodeRef-Fields as an array, and eventDispatcher.basicAuthentication=username:password for Basic Authentication)

type: int, required: yes, default: 4

Size of the thread pool that dispatches the events

Dispatcher properties


type: string, required: yes, default: http://localhost

Endpoint to be informed about the event. Also supports multiple URLs (comma-separated).

Adds additional parameters when available:

  • eventType: Name of the event (always; since 1.0)
  • id: ID of the affected object, unique per object type (on assets, nodes, users and usergroups; since 1.0)
  • name: Name of the affected object, non-unique (on assets, nodes, users and usergroups; since 1.3)
  • fileName: Original file name of the asset (on assets; since 1.3)
  • node: The node an asset was added to or removed from (only AssetAddedEvent and AssetRemovedEvent, since 1.8)

Example: http://pim.brix.ch/event-handler/celum.do?eventType=AssetAddedEvent&id=1337&name=Ponies&fileName=Ponies.jpg


type: string, required: no, default: -, since: 1.10

Allows you to include arbitrary headers, e.g. eventDispatcher.header.Authorization=My$ecretTok3n

Only pass on events that originate from an asset/node that this user can see


type: (list of) long, required: no, default: -, applies to: eventFilterByNode

Only pass on events that originate in a certain node (recursively)


type: (list of) long, required: no, default: -, applies to: eventFilterByNodeType, since: 1.7.1

Only pass on events that originate in a certain node type


type: (list of) long, required: no, default: -, applies to: eventFilterByMetadataUpdated, since: 1.9.1

Only pass MetadataUpdatedEvents when one of the specified infofields have changed. Does not affect other event types.


type: string, required: no, default: -, applies to: eventFilterBySearchExpression, since: 1.12.0

Only pass AssetEvents whose asset satisfies the configured SearchUtil2 expression. Does not affect other event types.
