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 | ||
|---|---|---|
| ||
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.

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.
The full structure of the event message Default headers
Every message contains these default headers:
"namespace": ns
Whereasnsis 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 | ||
|---|---|---|
|
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.
The full structure of the event message routing key is like this:
...
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/nsprefix) 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.
...
.*.global.app.com.mycompany.myapp.data.*
The body of most property event messages has a structure like this:
| Code Block |
|---|
pipeforce.event.property.deleted.{path} |
.updated
This event message is send after a property was updated.
The full structure of the event message routing key is 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.
