Event Trigger

Admin tools ::: tool_trigger
Maintained by Catalyst IT
This plugin plugin allows site administrators to trigger external actions such as an http request or email when certain events happen in Moodle. Filters can be added to check if the event meets certain conditions and actions(email/http post) can include information contained within the Moodle event. Lookups can also be added to the workflow to allow information not contained within the Moodle event to be exposed to the external action.

Event Trigger

The Event Trigger allows Moodle Events to be monitored and a workflow to be triggered when that event occurs.
One of the main use cases of this plugin is to allow Moodle events to trigger actions in external systems.

Each workflow is made up of a series of steps. Steps can be things like:

  • Using event data to lookup user and course information
  • Filtering data based on a set of conditions
  • Performing an action like sending an email or Posting data to a HTTP endpoint or external API.

More configuration documentation can be found at the following link:

More Information on Moodle events can be found in the Moodle documentation at the following link:

    I would like to set up an event trigger on course completion - which appears easily done. The only problem I have is that I wish to trigger different actions for course completion on different courses. Is this possible with this plugin?

    @Hossein/@Kushan - probably best that you install the plugin and test it to see if it does what you want.

    When will be new version release for Moodle 3.11?

  • Sat, Oct 9, 2021, 5:12 AM
    @Rehan - the latest version of all our plugins is always in our github repositories - we do not regularly update the moodle.org plugins db with the latest version of all our plugins and do not provide dates/times of release dates - for some plugins we rely on the community to test the plugin and let us know if it works in a newer release - please test the plugin yourself in 3.11 and report any issues you have to our github tracker - (i;m not currently aware of any issues that would prevent it from working in 3.11)

    Does anyone know if installing this plugin in 4.0 will work.. We're forced to upgrade ASAP.

    @ben - we're not aware of any reason it wouldn't but as always, latest version of our plugins are in github and please report any issues you find to our issues tracker.

    Hello, I can see that this plugin is essential for those who need a more automated Moodle. However, I have a situation where I want to send an email to the student when he accesses the course certificate. I can get the course name through the plugin, but I can't get the username. The "Lookup Course" parameter works correctly. The parameter "Lookup User" I can't make it work. I have Moodle 3.11.5. Would it have anything to do with it?

    The User Lookup DOES NOT WORK as the last commentor said. We've looked at the source code and cannot seem to find what the problem is. THIS WILL NOT SEND EMAILS TO ENROLLED USERS IN ITS CURRENT STATE

    @Joe - if you have internal development capabilities, feel free to do some further investigation and submit a pull request if you track it down! - otherwise we're in the process of re-developing this plugin here: https://github.com/catalyst/moodle-tool_dataflows

    Feel free to try that one out and see if it works better for your needs!

    @Ritik - as mentioned in the comments above, our main recent focus has been on a new plugin to replace this one called "tool_dataflows", however we welcome pull requests against the main tool_trigger repository if you have development capabilities and are able to help! - if not, you might want to try out our new plugin and see if it meets your needs. (it isn't published in the plugins db yet, only in github.)
