Available triggers

Note that due to their nature, each script only supports certain triggers. For example it wouldn’t make sense for a script enforcing the content of a post to trigger when a user is added to a group.

All of the available triggers are mentioned in the “Available scripts” table above.

Most of the triggers are self-explanatory, but here are a couple that may need a little more detail:

Trigger Description
After post cook Triggers after a post is rendered for display
API Call Triggers when a certain API endpoint is called
Stalled wiki Triggers when a wiki hasn’t been edited for a while
Stalled topic Triggers when a topic has not received replies after a certain time
Topic Triggers when a reply is made to a topic

If you need any clarification on any others please feel free to ask below. :slight_smile:

More scripts and triggers to come!

Custom Automations

You can also create custom Automations. :partying_face: Check out our developer’s guide for more information - Create custom Automations

:discourse2: Hosted by us? This plugin is available on our Business and Enterprise plans. Automation | Discourse - Civilized Discussion


Just to note, I’ve updated the OP with a table of all the existing Automations and their accompanying triggers. :+1:

(I’m also hoping to add more guides too, as the one for ‘Add user to group…’ looks a bit lonely all by itself :slight_smile:)

There are a couple more walkthroughs added for 'Append last edited by' Automation and 'Append last checked by' Automation. :tada:

And a brand new script, User Group Membership through Badges. :partying_face: That one is pretty hot off the press so if you try it out, let us know how you get on. :+1:


Now I feel myself very very… not stupid, but close. Where can I build up automations? Under plugins I can only enable or disable Automation.

After enabling the plugin, you should see new item here:

It might require refreshing the page to see it.


Aaand now I feel myself really stupid :man_facepalming:

I’ve been stuck on that one before :slight_smile:

Replies to this topic should probably get set to auto delete after 30 days. At least this reply should.

We no longer do that for official plugin topics. Too much good information has been lost to the topic timers. We now curate them manually and split any significant discussions into separate tagged topics (as well as encourage people to start separate topics to begin with). :+1:


A post was split to a new topic: Automation to close Solved topics and post a template response

:information_source: Discourse Automation has now been bundled with Discourse core, so this plugin will no longer need to be installed separately. :partying_face:

:discourse2: Hosted by us? This change will not affect you in any way. :+1: If you are on the Business or Enterprise plans, you can continue to enjoy this plugin and not worry about a thing.


Is there an automation script that can change Category? I’d like to use it to make a more flexible “Schedule Publishing” system.

I’m imaging that the script would

  • run periodically, and
  • check for topics in a given category which have some marker in a reply (like, marked as solved or reply contains certain text, like “PUBLISH”).
  • If the date of that reply (or “solved” status) is longer ago than a given offset (like, yesterday, or a week),
  • delete all replies
  • move to given category
  • optionally, add configurable tags

A more sophisticated version might look for a date/time in the trigger reply, and publish if it is now after that date/time.

It also might look for the target category in that post (with script config for allowed target categories). And for that matter, tags.
