Node reference

Overview

Extension After Install is a Trigger in Joomla Events › Extension Events. After an extension installs successfully.

New extension is on disk and registered; use for default config or migrations.

Each run also includes who was logged in at the time and what kind of item was involved — see audit_user and audit_type in Payload Fields below.

This trigger is not connected yet — flows using it will not run until JOrchestrator adds support for this Joomla hook.

When this trigger fires, JOrchestrator starts the flow and passes the incoming event or request data to the next connected step. Configure filtering, payload shape, and security on the Design tab.

Why use this node

Extension After Install is a trigger in the Joomla Events › Extension Events group. Triggers start a flow. They listen for an external signal — a CMS event, inbound HTTP call, payment notification, or schedule — and pass the incoming data to the first downstream step.

Typical reasons teams add Extension After Install to a flow:

  • Automate backend work when Joomla fires ExtensionAfterInstall
  • Notify administrators or sync external systems on this CMS lifecycle event
  • Enrich or validate CMS data before it is persisted
  • Audit user, content, or extension activity without custom plugins

When it runs

After an extension installs successfully.

Example workflows

Common patterns on the canvas:

  1. Extension After Install → Send Notification (admin alert)
  2. Extension After Install → Insert Row (audit log)
  3. Extension After Install → If → Send Email / Update Article

Properties panel

The designer shows these tabs for this node:

TabPurpose
InfoPlain-language description and output payload fields for downstream steps
DesignTrigger configuration and payload schema

System (automatic — not edited by the user)

These fields are managed by the designer or runtime — you do not type into them directly:

Property keyLabelTypeRequiredVisible whenNotes
_nodeIdNode IDnode-idNo——

User-configured — General tab

Property keyLabelTypeRequiredVisible whenNotes
labelLabeltextNo—Node label

CMS site configuration (not on this node's properties panel)

Credentials, API keys, mailers, SMTP, and integration defaults are configured in the CMS plugin under Node Configuration, not per step on this node. Link the flow to a domain before testing CMS-backed fields.

Output payload fields

After this step runs, later nodes can reference these fields using placeholders such as {{extension_after_install.context}}.
