# Events

Events are automatically created for a resource when a specific action happens (i.e. `orders.place`). When a [webhook](https://docs.commercelayer.io/core-api-reference/webhooks) is listening to that action's topic and the subscribed event occurs, Commerce Layer sends a `POST` request to the webhook's callback URL, and the associated [event callback](https://docs.commercelayer.io/core-api-reference/event_callbacks) is created.

Events can be [included](https://docs.commercelayer.io/developers/including-associations) when fetching the resources that support them to inspect each recorded action.

### Retriggering events

Events are automatically triggered at creation time, notifying all listening webhooks. If, for some reason, you want to force the firing of an existing event manually, you can patch it with the `_trigger` attribute set to `true` (you need to use [integration](https://app.gitbook.com/s/-LgByaSP8eKjad-MIuHE/api-credentials#integration) API credentials) — the event will be immediately triggered, regardless of its uniqueness.

Create and delete operations are not allowed on this endpoint. You can only fetch a list of events or a specific single one, which can also be updated in order to trigger it manually or update common attributes (metadata, references, etc.).
