I just want to call an event observer when the event is dispatched via the REST API. Like if an order is placed from a mobile application, only then the sales_order_save_afterObserver should be called.

How do I write code for the same in events.xml? Or do we have to write somewhere else?

You have to place a events.xml in the webapi_rest area: app/[Vendor]/[Module]/etc/webapi_rest/events.xml

By placing the events.xml in the webapi_restdirectory the observer only listens to events dispatched in that area.

You can read about the areas and events in the devdocs.

  • @zus You'll need to inject \Psr\Log\LoggerInterface to write to the log. WIth $observer->getEventName() you can get the current event name.

You can declare your observer at the following location to call it via the REST API only.

app/code/Vendor/Module/etc/webapi_rest/events.xml
