Missing Gateway and Service Events

[AugustMiller]

What happened?

Description

Events are not currently emitted by craft\commerce\base\Gateway or craft\commerce\services\Gateways when saving a Gateway’s configuration.

Craft typically emits events from the service class when saving Project Config-bound changes (beforeSave when modifying values, then afterSave in a PC event handler). The model events appear to be less consistently triggered…

Steps to reproduce

1. Add a listener in a custom module:

   use craft\events\ModelEvent;
   use craft\commerce\base\Gateway;
   use yii\base\Event;
   
   Event::on(
      Gateway::class,
      Gateway::EVENT_BEFORE_SAVE,
       function(craft\events\ModelEvent $event) {
           Craft::dd('Got it!');
       }
   );

2. Save a new or existing gateway

Expected behavior

• Using the example code, the page is halted.
• I should also be able to listen to events from the service class, i.e. craft\commerce\services\Gateways::EVENT_BEFORE_SAVE_GATEWAY.

Actual behavior

No event is triggered.

Thanks for reporting. This is the same for some other project config based settings. Added this to the list for Commerce 5.x.

Others will include:

• Order Statuses
• Line Item Statuses
• Gateways
• Emails
• PDFs
• Product Types

Keeping this issue open until all services get the improved event handlers. Tracking the services here: #3224 (comment)

COM-273 Add more Gateway and Services events

#3885 Created, but not sure of the utility of these events so they have been placed on the backlog at low priority.

Happy to hear how others would want to use these events if they existed.
