An event message key (also known as topic) is a routing key pattern of an event message which is sent after a known event in PIPEFORCE happened and . This key always starts with prefix pipeforce.event, followed by the concrete event type.

It can be used to listen and send push notifications every time such an event happens or to register a pipeline listener and listen for such an event to a trigger a pipeline execution.

Here is an example how to add such an event message listener to a pipeline. As soon as the pipeline got saved in the property store, the listener is activated:

Code Block
languageyaml
pipeline:
  - message.listen:
      key: pipeforce.event.workflow.#
      
  - mail.send:
      to: admin@company.tld
      subject: A workflow event happened.

Pattern matching

When registering a listener for an event key, also patterns pattern matching can be used in the event key:

  • * = Stands for a single word up to the next period .

  • # = Stands for multiple words with multiple periods in between.

For example : the event key from above pipeforce.event.workflow.# matches all workflow event messages while pipeforce.event.workflow.*.my.app matches only workflow event messages inside the app my.app.

Here is the reference of these event message keys (also known as topics):

Table of Contents
stylenone

pipeforce.event.app

This topic group forwards all important events related to app management.

.install.finished

This event message is send after an app

Default headers

Every message contains these default headers:

  • "namespace": ns
    Whereas ns is the namespace this event happened inside. Cannot be changed for security reasons.

  • "content_type": application/json
    An event message body is always of type JSON.

Reference Documentation

Here is the reference of these event messages and their keys (also known as topics):

Table of Contents
stylenone

pipeforce.event.app

This topic group forwards all important events related to app management.

.install.finished

This event message is send after an app was successfully installed.

...

Every property topic key can additionally optionally contain dynamic variables which will be replaced at runtime such as:

  • {appName}

...


  • Will be replaced by the name of the app

...

  • , the related property is stored inside

...

  • . For example

...

  • io.pipeforce.myapp

...

  • .

  • {

...

  • propertyPath}

...


  • The namespace relative path (= no /pipeforce/ns prefix) of the related property whereas slashes in path of property will become dots. Dots and special chars in origin path will be replaced by underscores. Everything in path is lower-cased

...

.created

This event message is send after a new property was created.

...

  • . For example ns.global.app.com.mycompany.myapp.data.
    This way also pattern matching filtering can be applied on the path level. In order to listen on any property event on any property inside the data folder of your app you could use a key like this:

    Code Block
    pipeforce.event.property

...

.deleted

This event message is send after a property was deleted.

The full structure of the event message routing key is like this:

Code Block
pipeforce.event.property.deleted.{path}

.updated

This event message is send after a property was updated.

...

  • .*.global.app.com.mycompany.myapp.data.*

The body of most property event messages has a structure like this:

Code Block
pipeforce.event.property.updated.{path}

.comment.created

This event message is send after a comment was added to a property.

The full structure of the event message routing key is like this:

Code Block
pipeforce.event.property.comment.created.{appName}

.comment.updated

This event message is send after a comment was updated to a property.

  • correlationId = In case this event is part of an async execution, this is the id of the execution.

  • namespace = The namespace this event happened inside.

  • payload = A JSON which contains more information about the related properties whereas origin and target can also be null depending on the event type. Their attributes are:

    • uuid = The uuid of the related property.

    • path = The path of the related property.

    • type = The content type of the related property.

    • value = The value of the related property.
